Assuming that the resistance of the meters are negligible, what will be the readings of the ammeters `A_(1)` and `A_(2)` in the circuit shown in Fig.

Explanation

Here, in circuit, the diode is reverse biased. It offers infinite resistance. Hence no current flows through the upper resistance of `10Omega`. Therefore, the reading of ammeter `A_(1)` is zero.
Reading of ammeter `A_(2) = (2V)/(10Omega)=0.2A`
