Q2. What is powe r?
Ans. 
Power is the rate at which work is done or energy is transferred.
• Power is measured in watts (W)

• It is calculated as the product of voltage and current (P = V x I)

• Power can also be calculated as the rate of energy transfer (P = E / t)

• Higher power means more work can be done in a shorter amount of time
