Calculation of Current in the Circuit with Zener Voltage
- Zener Voltage: Given that the magnitude of the zener voltage is 4.9V.
- Reverse Saturation Current: Given that the reverse saturation current is 5 microamperes.
- Formula: The current in the circuit can be calculated using the formula I = Vz / R, where I is the current, Vz is the zener voltage, and R is the resistance in the circuit.

Calculation:
- Current (I) = Zener Voltage (Vz) / Resistance (R)
- Current (I) = 4.9V / R

Using Reverse Saturation Current:
- The reverse saturation current is the minimum current required for the zener diode to start conducting.
- When the zener voltage is applied in reverse bias, the zener diode conducts current greater than the reverse saturation current.
- The current flowing through the zener diode will be the sum of the reverse saturation current and the current calculated using the formula above.

Final Calculation:
- Total Current = Reverse Saturation Current + Current from Zener Voltage
- Total Current = 5μA + (4.9V / R)
By calculating the total current flowing through the circuit using the given zener voltage and reverse saturation current, you can determine the overall current and ensure the zener diode operates within its specified limits.
