The current in a resistor is 5.0 A, and its power is 60 W. What is the voltage?
alexandr1967 [171]

The voltage on a resistor will be "12 V".

According to the given question,

Current,

  • I = 5.0 A

Power,

  • P = 60

As we know the formula,

→ Power (P)= Current(I)\times Voltage (V)

or,

→              V = \frac{P}{I}

By putting the giving values, we get

→                  = \frac{60}{5}

→                  = 12 \ V

Thus the solution above is right.
