Question

two resistors of 12 ohm and 13 ohm are connected in series to a 5v battery.Voltmeter is placed on 12 ohm resistor.Find its reading.

Answer 1

Answer:

2.4V

Explanation:

R¹ = 12Ω

R² = 13Ω

V= 5V

R = R¹+R²

R= 12+13

R=25

V=IR

I= V/R

I = 5/25

I=1/5

I= 0.2A

Now, for 12Ω resistor

V=IR

V= 12× 0.2

V = 12× 1/5

V= 2.4V
