Question

When a 12 v battery is connected across an unknown resistor there is a current of 25mA in circuit. Find the value of resistance in resistor

Answer 1

hloo dear..!

Given ..
v = 12 v
I = 25 mA
which is equal to = 25 x 10 power -3


Now resistance = v / I =12/ 25 x 10 power -3
4.80ohms
= 4.8 k ohms



hope it helps
