Questions
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 resistance R, connected in series with the diode for obtaining maximum current?
detailed solution
Correct option is B
The current through circuiti=PV=100×10-30.5=0.2 A∴ Voltage drop across resistance = 1.5 - 0.5 = 1 V⇒R=10.2=5 ΩTalk to our academic expert!
