Basic Electrical Mcqs


Q.  Which of the following quantities consists of SI unit as WATT ?

a. Force
b. Charge
c. Current
d. Power


ANSWER: See Answer
 
The SI unit of power is the watt and it is discover by the Scottish Engineer James Watt. Power is the rate of consumption of electric energy. So, it is equivalent to joules per second.
