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

Option C (80 ohms) is the right answer.

Step-by-step 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=(V)/(I)`

On substituting the values, we get

⇒
`=(120)/(1.5)`

⇒
`=80 \ ohms`
