If an unregulated voltage of 10 V is regulated by a Zener diode of rating 4.7 V-1W calculate minimum resistance to be connected to the circuit for safe current.

The maximum output voltage of an unregulted voltage source is 10V. A Zener diode of rating 1 W is connected in reverse bias with this voltage source through a resistance R. The Zener diode will be burnt if R is less than 24 Omega . Find the maximum value of Zener voltage (in volt ) of the diode.

When a diode is forward biased, it has a voltage drop of 0.5 V. The safe limit of current through the diode is 10 mA. If a battery of emf 1.5 V is used in the circuit, the value of minimum resistance to be connected in series with the diode so that the current does not exceed the safe limit is :
