FAQs on Numerical: Electricity and Electric Power Video Lecture - Class 10

1. What is electricity and electric power?

Ans. Electricity is a form of energy resulting from the flow of electric charge. It is used to power various appliances and devices. Electric power refers to the rate at which electric energy is transferred or consumed.

2. How is electricity generated?

Ans. Electricity can be generated through various methods such as burning fossil fuels, nuclear power, or harnessing renewable energy sources like wind, solar, and hydro power. These methods involve converting mechanical, chemical, or thermal energy into electrical energy.

3. What are the units used to measure electric power?

Ans. Electric power is measured in watts (W). Kilowatts (kW) are commonly used for larger applications, and megawatts (MW) or gigawatts (GW) are used for power plants or large-scale generation.

4. What is the difference between AC and DC electricity?

Ans. AC (alternating current) electricity periodically changes its direction, commonly used in households and transmitted through power grids. DC (direct current) electricity flows in a single direction and is often used in batteries and electronic devices.

5. How is electric power calculated?

Ans. Electric power can be calculated using the formula: Power (P) = Voltage (V) x Current (I). The unit for electric power is watts, and it represents the rate at which energy is transferred or consumed.
