Question

Calculate the value of the resistor in the given circuit.

Answer 1

Given Data:

Potential difference of the source (V) = 9 V

Electric current reading in the ammeter (I) = 0.2 A

Formula:

According to Ohm's Law, the electrical resistance (R) is given by the formula:

R = `V/I`

= `9/0.2`

= `90/2`

= 45 Ω

The value of the resistor in the given circuit is 45 Ω.
