Question

When a device is used in a circuit in which the voltage is 81 v The current flowing through the device is 3 A what is the resistance of The Device

Answer 1

= 27Ω

Step-by-step explanation:

The voltage of a device = Resistance × Current

V=RI

Making R the subject of the formula we have R= V/I

Thus resistance = Voltage/ Current

V= 81 V

I = 3 A

Using these values in the formula for resistance we can then find the resistance of the device as follows.

R = 81 V/ 3 A

= 27Ω
