Capacitors in DC Circuits Lab

The lab aims to study the charging and discharging of a capacitor and draw the waveform.

Apparatus and Components Required

1 Kit KL 21001
2 resistors of 100 Ω each
1 capacitor of 10 µF
1 bread board
1 multimeter
1 function generator
1 CRO (Cathode Ray Oscilloscope)
Connecting wires

Circuit Making on Bread Board

Connect a 100 Ω resistor and a 10 µF capacitor in a series circuit.
Adjust the function generator to produce a 1 KHz square wave.
Apply the input square wave to the circuit.
Connect CRO channel 1 to the input leads to observe the input square wave.
Connect CRO channel 2 across the capacitor to observe the output waveform.

Measuring Time Constant

The time constant τ is calculated by the formula τ = RC.
Measure the time constant for the circuit with one resistor and one capacitor.
Repeat the experiment for a circuit with two 100 Ω resistors in series and one 10 µF capacitor.
Record the computed and measured values of the time constant.

This lab experiment aims to study the charging and discharging of a capacitor in a DC circuit. It involves setting up a series circuit with a resistor and capacitor, and observing the waveform. The apparatus required includes a kit, resistors, capacitors, and a multimeter.
