Question

find out volt when current is 40 mili ampere and resistance is 8 ohms

Answer 1

I = 40 × 10^-3 A
R = 8 ohm
V = ?

V=IR
V=40×10^-3×8
V=3.2×10^-1 V
(OR)
V=0.32 V

Answer 2

I = 40 mili amp. = 40 * 10 ^ -3 amp.

R = 8 ohm.

V = I * R

= 40 * 10^-3 * 8

= 320 * 10^-3

= 3.20 * 10 ^ -1

= 0.32 V Ans
