The zener diode dissipates most power when the output current is zero, that is when no load is connected to the power supply. In order to prove the veracity or otherwise of this statement by designing a simple power supply with an input voltage of 13 V, and capable of delivering up to 1 A, with an output voltage of 10V. You are to sketch the circuit and calculate the value of the limiting resistor, power rating of the limiting resistor, the power rating of the 10V zener diode used in the circuit on no load condition, the power rating of the Zener diode with a load resistance of 2kΩ. Assume a current of 10mA flows through the zener diode to keep it in zener breakdown

Question

The zener diode dissipates most power when the output current is zero, that is when no load is connected to the power supply. In order to prove the veracity or otherwise of this statement by designing a simple power supply with an input voltage of 13 V, and capable of delivering up to 1 A, with an output voltage of 10V. You are to sketch the circuit and calculate

  1. the value of the limiting resistor,
  2. power rating of the limiting resistor,
  3. the power rating of the 10V zener diode used in the circuit on no load condition,
  4. the power rating of the Zener diode with a load resistance of 2kΩ.

Assume a current of 10mA flows through the zener diode to keep it in zener breakdown.
