Question

when a current passing through a resistor is doubled power will be quadrupled what about the power if voltage is doubled​

Answer 1

Answer:

ANSWER

Ohm's law states that the electrical current (I) flowing in a circuit is proportional to the voltage (V) and inversely proportional to the resistance(R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Answer 2

Answer:

THE POWER WILL QUADRUPLE

Explanation:

THIS IS BECAUSE P=V^2/R

IF V IS REPLACED BY 2V

THEN V^2  WILL BECOME (2V)^2 = 4V^2

THERE FORE POWER WILL BE QUADRUPLE
