Question
In the circuit shown, assume that the diodes and are ideal. The average value of voltage (in Volts), across terminals 'a' and 'b' is ______.
Correct answer
4.85 to 5.15
Solution
The input voltage is .
Case 1: Positive half cycle ():
is forward biased (ON) and is reverse biased (OFF).
Node 'a' is connected to , so .
Node 'b' is connected to ground through and to node 'a' through .Case 2: Negative half cycle ():
is reverse biased (OFF) and is forward biased (ON).
Node 'b' is connected to , so .
Node 'a' is connected to ground through and to node 'b' through .Average Value:
