Question

If a 12v battery is connected to three resistors 1 ohm, 2 ohm, 3 ohm in series. What is the total current and potential difference in the current?

Answer 1

 it is equal to 6 omh

Answer 2

V = 12
R1 = 1 ohm
R2 = 2 ohm
R3 = 3 ohm

V = IR
12 = I * 1+2+3
12 = I * 6
12/6 = I
2 = I

V1 = I*R1
V1 = 2*1
V1 = 2

V2 = I*R2
V2 = 2*2
V2 = 4

V3 = I*R3
V3 = 2*3
V3 = 6

V = V1 + V2 + V3
12 = 2+4+6
12 = 12
