Question

A current of 2 ampere flows through a conductor of resistance 4.5 ohm. Calculate the potential difference at the ends of the conductor

Answer 1

Answer:

9 volts

Explanation:

Current = 2I

Resistance of the conductor = 4.5ohm (R)

According to Ohm's law,

Potential difference = Current * Resistance

i.e. V = I * R

Therefore, Voltage = 2 * 4.5

= 9 volts
