(a)
Interpretation:
Time constant for the circuit should be calculated.
Concept introduction:
The product of RC is referred to as time constant for the circuit and is a measure of the time required for a capacitor to charge or discharge.
(b)
Interpretation:
The current, voltage drops across the capacitor and the resistor during a charging cycle at given times should be calculated.
Concept introduction:
The product of RC is referred to as time constant for the circuit and is a measure of the time required for a capacitor to charge or discharge.
Ohm’s law:
Ohm’s law describes the relationship among voltage, resistance, and current in a resistive series circuit.
V = IR
Connection between initial current and current across the capacitor (i) at given time during the charging is given by
The value of the voltage across the capacitor (Vc) at given time during the charging period can be given like this:
Vc = Voltage across the capacitor
Vs= Supply voltage
t = time
RC = time constant for RC circuit
(c)
Interpretation:
The current and voltage drops across the capacitor and the resistor during a discharging cycle at time 10 ms should be calculated.
