What are the readings of the ammeters $A_{1}$ and $A_{2}$ shown in figure (45-E4). Neglect the resistances of the meters.

Open in App

Solution

The diode is reverse biased. Hence the resistance is infinite.

So, Current through $A_{1}$ is zero.

For $A_{2},$

Current = $\frac{2}{10} = 0.2$ Amp.

What are the readings of the ammeters A1 and A2 shown in figure (45-E4). Neglect the resistances of the meters.

The diode is reverse biased. Hence the resistance is infinite. So, Current through A1 is zero. For A2, Current = 210=0.2 Amp.
