In the given circuit, what is the current ( in A ) through the battery?

Correct answer

Step-by-step solution

In the given circuit diode D 2 is reverse biased, so it will not conduct. Diode D 1 and D 3 are forward biased, so they will conduct, Thus the equivalent circuit is ∴ R net = ( 4 + 4 ) × 16 ( 4 + 4 ) + 16 = 8 × 16 24 = 16 3 Ω ∴ current through the battery, I = V R net = 16 16 3 = 3 A
