Correct Answer - Option 1 : [M
1 L
2 T
-3]
The correct answer is option 1) i.e. [M1 L2 T-3]
CONCEPT:
-
Power: The rate of work done by an electric current is called power. It is denoted by P.
- The SI unit of power is the watt (W).
Power dissipation is given by:
Power, P = VI
Where V is the potential difference across resistance, I is current flowing.
EXPLANATION:
-
Power is the electrical work done per unit time.
Power = work done/time
[Power] = [work]/[time] = [M L2 T-2]/[T] = [M1 L2 T-3]
