Electric Power:
Electric power is the rate at which electric energy is transferred or consumed in an electric circuit. It is the amount of work done per unit time in an electrical circuit. Electric power is measured in watts (W).
Definition:
Electric power is defined as the rate at which electric energy is transferred or consumed in an electric circuit. It is the product of current and voltage in a circuit.
Formula:
The formula to calculate electric power is:
Electric Power (P) = Current (I) × Voltage (V)
SI Unit:
The SI unit of electric power is the watt (W). It is named after the Scottish engineer James Watt. One watt is equal to one joule per second.
Power of Lens:
The power of a lens refers to its ability to bend light rays passing through it. It is a measure of the lens's focusing strength. The power of a lens is used to determine its ability to converge or diverge light.
Definition:
The power of a lens is defined as the reciprocal of its focal length. It is a measure of the lens's ability to bend light rays. The power of a lens is positive for a converging lens and negative for a diverging lens.
Formula:
The formula to calculate the power of a lens is:
Power (P) = 1 / Focal Length (f)
SI Unit:
The SI unit of power of lens is the diopter (D). It represents the reciprocal of the focal length of the lens in meters.
Difference:
The main difference between electric power and power of lens is their application and the quantities they measure. Electric power is used to measure the rate at which electrical energy is transferred or consumed in a circuit, whereas the power of a lens is used to measure the lens's ability to bend light rays.
Electric power is calculated using the formula P = I × V, where I represents the current flowing through the circuit and V represents the voltage across the circuit. On the other hand, the power of a lens is calculated using the formula P = 1 / f, where f represents the focal length of the lens.
In conclusion, the question in set 3 of the CBSE paper 2020 refers to electric power, while the question in set 2 refers to the power of a lens. The SI unit for electric power is the watt, and for the power of a lens, it is the diopter.
