There are many ways to reduce greenhouse gas emissions from the industrial sector, including energy efficiency, fuel switching, combined heat and power, use of renewable energy, and the more efficient use and recycling of materials.

But the greenhouse gas molecules absorb the infrared light, and then re-radiate some of it back to the Earth’s surface. This makes the surface hotter so it radiates more light, thus establishing an equilibrium at a higher temperature. This process is known as the Greenhouse Effect.

As you improve the energy efficiency of your home, you need less electricity and thus rely less on carbon-intensive power plants. This reduces your home’s demand from the plant, which in turn benefits the environment by reducing their carbon dioxide emissions.

If not, extra energy is usually stored: Hydel power plants automatically store energy – they can reduce flow to the turbines and the water will accumulate in the reservoir. The water is an energy buffer. Some power stations pump water into temporary reservoirs.

Electricity always returns to the source of the power supply (a transformer or substation). When electrical current cannot flow through a neutral conductor, due to some type of damage or defect in the circuit, more current will use a path through the earth to return to the power supply.

As the National Agricultural Safety Database emphasizes, electricity takes the path of least resistance. In the case of electricity, that’s a beeline straight to the ground.

With net metering, you can receive utility bill credits for the electricity that your solar panels produce. If you do generate more electricity than you use in a year, utilities in some states will let you carry credits over into future years, while others will reduce your credits.

A household can be disconnected from the grid at home, but those consumers will still use the grid when they drive down lit streets, go to work and school, shop and eat out. There is a societal element of electricity systems that has always existed, but never been noticed.

During night, most of the inductive load are turned off which give rise to capacitive current in the line. We know that capacitor charging current leads to voltage drop across the line inductor of the transmission system which is in phase with the sending end voltages.

If the frequency deviates from desired generators start to go out of synchronism which triggers events in the power system causing voltage, frequency, power imbalance due to which a power system will collapse.

Following the loss of generation, the frequency falls, due to the imbalance in generation and demand, and the voltage falls due to a reduced number of circuits out of the area. At the same time the amount of power out of the area also reduces and the rate of change of frequency is high.

Too much electricity, low demand If too much electricity is fed into the grid in relation to the quantity consumed, the electrical frequency increases.

Note: Frequency instability usually results from variations of circuit elements or parameters caused by corrosion and changing environmental conditions, such as temperature, humidity, atmospheric pressure, and vibration. In a given case, the exact cause of frequency instability is often unknown or undetermined. 2.

In AC electrical circuits, there are many components where many factors like current, voltage, impedance and frequency are correlated. Talking about inductive load, it’s inductive reactance is directly proportional to frequency of operation and thus since current is inversely proportional to the inductive reactance.

The power system delivery frequency in an electrical system will affect inductive and capacitive reactance, and will have very little effect on purely resistive loads. It will affect the power factor of the delivered voltage.

When you get into motors, transformers, and other non-resistive loads, the power may vary with frequency. It can certainly affect power. Reactive elements will take more or less (reactive) power with changes in frequency.

The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Frequency is the number of cycles that a voltage waveform repeats itself per seconds. A voltage with 0 frequency in effect is steady at a certain value which is also known as DC voltage. In case of transformer the voltage is proportional to applied signal freq.

Voltage and Frequency are generally independent i.e., there is no effect of frequency on voltage if you are not specifying the element across which you are measuring voltage. However, if you are talking about the voltage across a capacitor or an inductor there comes the difference.

This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease. Knowing any two of the three parameters allows us to calculate the third, unknown parameter.

Absolutely! A resistor is about to reduce the current and voltage. For example, when the current flows through the resistor, it will always generate a voltage drop, and which is mainly reflected in the decrease of the output current and the voltage.

If the resistor is in series with some other element, and they together are powered by a constant voltage source, then the voltage dropped across the resistor means there’s less voltage available for the other circuit element.

As electrons pass through a resistance, they lose energy as they interact with electrons in the conducting material. As energy is given up to the material, it gains thermal energy so its temperature rises. The moving electrons lose potential energy and hence there is a drop in voltage.

To reduce voltage in half, we simply form a voltage divider circuit between 2 resistors of equal value (for example, 2 10KΩ) resistors. To divide voltage in half, all you must do is place any 2 resistors of equal value in series and then place a jumper wire in between the resistors.

This is a USB 5V to 1.5V/3V Step-Down Converter Circuit. It is used instead of a normal AA battery. In the circuit, we use LM317 DC voltage Regulator. To reduce the 5V input voltage from USB Port to the 1.5V at 1.5A maximum output.

You can use any 3 resistors with same value connected in series to 5V and take voltage from 2 of them. So it will be 2/3 from 5V = 3.333V – very close to 3.3V.

Connect 12 v to pin 1 ,pin 2 is the ground and pin3 gives 5v. Don’t want to use IC or not getting it,use a voltage divider using 2 resistors and you are done with it. Connect 12 v across the series combination of 4.7k ohm and 6.8k ohm(readily available standard ) resistor and take the output across 4.7k ohm.

PLace two resistors in series with the 2nd resistor value (5/7) of the first resistor value. Place the resistors between 12v and ground and then you will get 5v at the point between them. This is a very crude way of doing it. It is unregulated so the voltage out will be dependent of voltage in.
