Ohm's law states that voltage is directly proportional to current when resistance is constant (V=IR).

• Voltage (V) is equal to the product of current (I) and resistance (R)

• It is used to calculate the relationship between voltage, current, and resistance in an electrical circuit

• It helps in determining the amount of current flowing through a circuit for a given voltage and resistance

Transformers are electrical devices used to step up or step down voltage levels in power systems.

• Transformers are used to increase (step up) or decrease (step down) voltage levels in electrical power systems.

• Step up transformers are used to increase voltage for long distance transmission, while step down transformers are used to decrease voltage for distribution to consumers.

• Transformers work on the principle of electromagnetic induction, where changing current in one coil in...read more

A thermal power plant is a facility that generates electricity by converting heat energy into electrical energy.

• Uses fossil fuels like coal, oil, or natural gas to generate heat

• Heat is used to produce steam, which drives a turbine connected to a generator

• The generator converts mechanical energy into electrical energy

• Common type of power plant used for electricity generation worldwide

To service a generator, follow these steps:

• Inspect the generator for any damage or wear and tear

• Check the oil level and change if necessary

• Inspect and clean the air filter

• Check the fuel level and add if necessary

• Inspect the spark plugs and replace if needed

• Test the battery and replace if necessary

• Run the generator for a few minutes to ensure it is working properly

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers consist of two coils of wire, known as the primary and secondary windings.

• The primary winding is connected to the source of electrical power, while the secondary winding is connected to the load.

• Transformers can step up or step down voltage levels depending on the number of turns in the coils.

• They are used in power distribution sys...read more
