Question
Calculate the current through the circuit and the potential difference across the diode shown in figure. The drift current for the diode is $20\mu\text{A}.$
✓
Answer
Current in the circuit = Drift current
(Since, the diode is reverse biased $=20\mu\text{A})$
Voltage across the diode $=5-\big(20\times20\times10^{-6}\big)$
$=5-\big(4\times10^{-4}\big)=5\text{V}.$

A galvanometer has a resistance of $8 \Omega$ . It gives a full scale deflection for a current of 10 mA. It is to be converted into an ammeter of range 5 A. The only shunt resistance available is of $0.02 \Omega$ , which is not suitable for this conversion. Find the value of resistance R that must be connected in series with the galvanometer (Fig.) to get ammeter of desired range.
