Diodes Exercises
Exercise 1
An A.C. voltage of peak value
is
connected in series with a silicon diode and
load resistance of
. If the forward
resistance of diode is
(Third
approximation), find :
1. The peak current through diode.
2. The peak output voltage.
3. What will be these values if the diode is assumed to be ideal?
Exercise 2
Find the current through the diode in the circuit
shown in the circuit. Assume the diode to be ideal.
Exercise 3
Calculate the current through
resistor in the opposite
circuit. Assume the diodes to be of silicon and forward
resistance of each diode is
(third approximation).
Exercise 4
Determine current through each diode in the circuit shown below. Use the
simplified model (2nd approximation). Assume diodes to be similar.
Exercise 5:
Determine if the diode (ideal) in the opposite circuit is forward
biased or reverse biased.
