Question

A resistor is connected to a 36v power supply. An ammeter measures a current of 2.0 A going through it. Determine the resistance in ohm

Answer 1

R = 18 ohms

Explanation:

Given:

V = 36 volts

I = 2.0 A

R = ?

Use Ohm's law to solve for the resistance:

V = IR

or

R = V/I

= (36 volts)/(2.0 A)

= 18 ohms
