Question

The potential difference between the terminals of an electric heater is 60 V when it draws a current of 4 A from the source. calculate the resistance of the electric heater coil​

Answer 1

Answer:

Potential Difference (V) = 60 V

Current (I)= 4 A

From Ohm's law ,

               V = I * R

               60 = 4 * R

               R = 15 ohm

Therefore , Resistance of the electric heater coil is 15 ohms.
