The power used by a diode is found by a multiplying the diod

The power used by a diode is found by a multiplying the diode current times the diode voltage reading a voltmeter placed across the diodes leads reading an ammeter placed across the diode leads squaring the diode current and multiplying by the reverse resistance. Under normal operation in a circuit a zener diode is forward biased. True

Solution

9) power p = V* I

V represents diode voltage

I represents diode current

option (a) is correct

power used by a diode is simply product of diode voltage and diode current...

10)true

under normal operation the zener diode is forward biased.

under reverse breakdown region the zener diode works as voltage regulator...
