Detailed Solution

8 V

is the potential difference between the points B and C shown in the figure.
Given,
Current passing through the circuit,

I = 2 A

R_{AB} = 2 Ω

[

R_{AB}

R_{BC}

= resistances]

R_{BC} = 4 Ω

Potential difference between B and C is given by,

V = I \times R

[Where

V = voltage; I = current and R = resistances]

{= > V}_{Bc} = I_{BC} \times R_{BC}

{= > V}_{Bc} = 2 \times 4

= > V_{Bc} = 8 V

So, the Potential difference between B and C is

8 V
