Sequence of energy conversion is Heat energy → Mechanical energy → Electrical energy. Was this answer helpful?

Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

At last, the rotating turbines generate electricity for later use. This final process is mechanical energy converted into electrical energy. So, from this we can conclude that the correct sequence in a hydroelectric power station is kinetic energy converted to potential, which is later converted to mechanical energy.

What kind of power plant uses these steps: splitting of atoms/releasing energy, sun heats water, steam moves through pipes, turbines turn generators that put out electricity, steam causes turbines to spin. what is the role of a generator in a hydroelectric power plant?

The main components of an electric generator can be broadly classified as follows:

• Engine.
• Alternator.
• Fuel System.
• Voltage Regulator.
• Cooling and Exhaust Systems.
• Lubrication System.
• Battery Charger.
• Control Panel.

There are four stages in coal formation: peat, lignite, bituminous and anthracite. The stage depends upon the conditions to which the plant remains are subjected after they were buried – the greater the pressure and heat, the higher the rank of coal.

In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).

Electronics refers to reading changes in electrical properties as information. For example, a microphone changes sound pressure waves in the air to a changing electrical voltage. This process of changing one energy into another is called transduction, and devices that do it are called transducers.

An electric device is one that directly uses electrical energy to perform a task. Instead of just converting electrical energy into light, heat, or motion, electronic devices are designed to manipulate the electrical current in ways that adds meaningful information to the current.

Write the forms of energy into which electrical energy is converted by each device.

• Accept all reasonable responses. Possible answers:
• lamp—light energy and thermal energy;
• hair dryer—thermal energy and kinetic energy;
• toaster—thermal energy;
• TV—light and sound;
• CD player—sound.

For example, although your TV set’s remote control is a pretty complicated little electronic device, it contains batteries, which are simple electrical devices.

Safety Devices:

• Arc-Fault Circuit Interrupters (AFCI): Available as circuit breakers and receptacle.
• Surge Protective Devices (SPD): Surge Protective Devices protect against surges that can damage or reduce the lifespan of your electrical system and devices.
• Ground-Fault Circuit Interrupters (GFCI):
• Tamper Resistant Receptacles (TRR)

Explanation: electric fuse called as safety device because when more power is supplied then to break the circuit the fuse break it self and our device would safe ..

Short circuits are a major type of electrical accident that can cause serious damage to your electrical system. They occur when a low-resistance path not suited to carry electricity receives a high-volume electrical current. The result of a short circuit can be appliance damage, electrical shock, or even a fire.

Put Your Safety First

1. Disconnect the Electricity. First, disconnect the electricity to the source of the fire.
2. Use Baking Soda for Small Electrical Fires. If the fire began in an appliance or an overloaded cord, once you’ve unplugged the power source, toss baking soda over the flames.
3. Never Use Water While the Power Is On.
