The diode used in the circuit shown in the figure has a constant voltage drop of 0.5 V at all currents and a maximum power rating of 100 milliwatts. What should be the value of the resistor R, connected in series with the diode for obtaining maximum current
Text Solution
Verified by ExpertsThe correct answer is:
B
Voltage drop across diode 
;
Maximum power rating of diode 
and source voltage 
The resistance of diode ( 
)
And current in diode
Therefore total resistance in circuit ( 
)
And the value of the series resistor
