Answer 2

Answer:

V2 = 8V ; I2 = 0.8V

Explanation:

In series circuit, remember these key points:

1. Total Resistance = R1 + R2 + R3 + R4 ...

2. Total Voltage = V1 + V2 + V3 + V4 ...

3. Total Current = I1 = I2 = I3 = I4 ...

To get the total current, use R1 and V1 value to get I1.

I = V/R

I = 4V / 5 ohm

I = 0.8A --- this will also be the value of I2 since Current across a series circuit are of with the same values.

Getting the value of V2,

V = IR

V2 = (0.8A) (10 ohm)

V2 = 8V
