(a)
The average current.
(a)
Answer to Problem 29P
8.1 mA
Explanation of Solution
Given:
Voltage,
Resistance,
Capacitance,
Formula used:
It is known that
Where,
Calculation:
First calculate the time constant for the circuit:
Because there are two peaks per cycle, the period of the rectified voltage is
Because
Therefore, voltage will be the peak voltage.
So, the average current is
(b)
The average current for the given value of C.
(b)
Answer to Problem 29P
Explanation of Solution
Given:
Voltage,
Resistance,
Capacitance,
Formula used:
It is known that
Where,
Calculation:
First calculate the time constant for the circuit:
Because
Therefore, average voltage will be close to rms voltage.
So, the average current is
