The circuit contains two diodes each with a forward resistance of 50 Ω and with infinite reverse resistance. If the battery voltage is 6 V , the current through the 120 Ω resistance is _______ mA

Correct answer

0

Step-by-step solution

In this circuit D 1 will be forward bias and D 2 will be revers bias. ∴ There will be no current through D 2 and R 2 Apply KVL in circuit we get + 6 - 50 i - 130 i - 120 i = 0 i = 6 300   A = 6 300 × 1000   mA ⇒ 20   mA
