What is the current through the battery in the circuit shown below? (a) 1.5 A (b) 0.25 A (c) 1.0 A (d) 0.5 A

Answer: (d). Both diodes point the same way and are forward biased, so both 20 Ω branches conduct. Req = (20× 20)/(40) = 10 Ω I = 5/10 = 0.5 A So the answer is (d) 0.5 A.

P-N Junction Diode

What is the current through the battery in the circuit shown below?

Show answer and solution

Answer: (d)

Both diodes point the same way and are forward biased, so both $20\ \Omega$ branches conduct.
$R_{eq} = \dfrac{20\times 20}{40} = 10\ \Omega$
$I = \dfrac{5}{10} = 0.5$ A
So the answer is (d) $0.5$ A.
