Question

Calculate the resistance of a circuit with 1.5 A and 120 V. Use the appropriate formula from the list of formulas on the
whiteboard
A 60 watts
60 ohms
C 80 ohms

Answer 1

Answer:

Option C (80 ohms) is the right answer.

Explanation:

The given values are:

Current,

I = 1.5 A

Voltage,

V = I20 V

As we know,

⇒  $V=IR$

or,

The resistance will be:

⇒  $R=\frac{V}{I}$

On substituting the values, we get

⇒      $=\frac{120}{1.5}$

⇒      $=80 \ ohms$
