Two ideal diodes are connected to a battery as shown in the circuit. The current supplied by the battery is
  1. $0.75 \mathrm{~A}$
  2. zero
  3. $0.25 \mathrm{~A}$
  4. $0.5 \mathrm{~A}$

Solution

Here in circuit $D_1$ is forward bias and $D_2$ is reverse bias. Current will flow only in diode $D_1$

The current supplied by the battery
$i=\frac{5}{10}=0.5 \mathrm{~A}$
