In the given circuit, the current through the Zener diode is
Step 1: Given Data
Resistance of the resistor is and resistance of the another resistor is
Voltage of the battery is
Voltage of the Zener diode is
Let the voltage across the resistor be .
Step 2: Zener diode
Step 3: Calculate the Voltage
Let the voltage across the resistor be .
According to Kirchoff's law
Upon substituting the values we get,
Step 4: Calculate the Current
Therefore according to Ohm's law, the current across is
Similarly, the current through can be given as
Step 5: Calculate the net current
Hence, the current passing through the Zener diode can be given as
Hence, the correct answer is an option (B).
