Which statement correctly describes the relationship between power, voltage, and current?

if voltage is increased, and no other changes are made, power will decrease.

if voltage is increased, and no other changes are made, power will increase.

if current is decreased, and no other changes are made, power will increase.

in order to decrease power, voltage must be decreased.

Answer : If voltage is increased, and no other changes are made, power will increase.

Explanation :

The power of an electrical appliance is given by the three relations :

............(1)

Where

I is the current flowing

R is the resistance offered

V is the voltage

The relationship between the power, voltage and the current is given by equation (1).

Power is directly proportional to the voltage and the current.

So, the correct statement is (B) " If voltage is increased, and no other changes are made, power will increase ".
