(C) The circuit consists of a $2\,V$ battery,a diode,and a series resistor $R$ in a loop. Applying Kirchhoff's Voltage Law $(KVL)$ to the circuit: $V_{battery} = V_{diode} + V_{resistor}$ Given $V_{battery} = 2\,V$,$V_{diode} = 0.5\,V$,and the desired current $I = 5\,mA = 5 \times 10^{-3}\,A$. Substituting these values: $2\,V = 0.5\,V + I \times R$ $2 - 0.5 = 5 \times 10^{-3} \times R$ $1.5 = 5 \times 10^{-3} \times R$ $R = \frac{1.5}{5 \times 10^{-3}} = \frac{1500}{5} = 300\,\Omega$ Therefore,the required series resistance is $300\,\Omega$.

Medium

$A$ $2\,V$ battery forward biases a diode. There is a drop of $0.5\,V$ across the diode which is independent of current. Also,a current greater than $10\,mA$ produces large joule heat and damages the diode. If the diode is to be operated at $5\,mA$,the series resistance to be used is:

A
$3\,k\Omega$
B
$300\,k\Omega$
C
$300\,\Omega$
D
$200\,k\Omega$
