Question

When the switches are arranged so that the current through the battery is maximum, what is the voltage across points A and B –

• A. 4V
• B. 0V
• C. 1V
• D. 2V

Answer 1

Answer: (B)

0V

Answer 2

When S₁ is closed

current through the battery is maximum

i = $\frac{24}{1}$ = 24 Ampere

V_A – V_B = E – ir

= 24 – 24 × 1 = 0
