Question

when a 20V battery is coonected across an unknown resistor there is a current of 100mA in the circuit. find the value of resistance in resistor

Answer 1

HEY THERE!!;

Answer:. 200 ohms

Explanation:

First of all its important to know that

1000 mA= 1 A

therefore,

100mA =0.1 A

Given,

I= 0.1 A

V= 20V

R= ?

V= IR

therefore,

R= V/I

R = 20/0.1

R= 200 ohms
