Calculate the power dissipated by a resistor when the voltage across the resistor is 10 V and the current through the resistor is 1 A (P=IV). What is the resistance of the resistor (V=IR) ?

P = 10 W

R = 10 ohm

Explanation:

Given that

Voltage difference = 10 V

Current, I = 1 A

We know that

Voltage difference = Current x Resistance

ΔV = I R

Now by putting the values in the above equation

10 = 1 x R

R = 10 ohm

We know that, Power P given that

P = V I

Now by putting the values in the above equation

P = 10 x 1 W

P = 10 W

Power dissipated, P = 10 W

R = 10 ohm
