(C) In the given circuit,diode $D_1$ is reverse-biased because its p-terminal is connected to the negative terminal of the battery. Thus,$D_1$ acts as an open circuit $(OFF)$.Diode $D_2$ is forward-biased because its p-terminal is connected to the positive terminal of the battery. Thus,$D_2$ acts as a closed circuit $(ON)$ with zero resistance.The circuit simplifies to a series combination of the $20 \ V$ battery,the $2 \ \Omega$ resistor,the $3 \ \Omega$ resistor,and the $2 \ \Omega$ resistor (associated with $D_2$).The total effective resistance $R = 2 \ \Omega + 3 \ \Omega + 3 \ \Omega + 2 \ \Omega = 10 \ \Omega$.The current through the cell is given by $I = V / R = 20 \ V / 10 \ \Omega = 2 \ A$.

If the diodes are ideal in the circuit given below,then the current through the cell is (in $A$)
