Interpretation Introduction

## (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.

Interpretation Introduction

### (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 = IRConnection between initial current and current across the capacitor (i) at given time during the charging is given byi = Iinte-t/RTThe value of the voltage across the capacitor (Vc) at given time during the charging period can be given like thisVc=Vs(1−e(−t/RC))Vc = Voltage across the capacitorVs= Supply voltaget = timeRC = time constant for RC circuit
