Charging & Discharging of Condensor with 2 meters

The Charging & Discharging of Condenser with 2 meters apparatus is designed for studying the behavior of a capacitor (condenser) as it charges and discharges through a resistor, allowing measurement of voltage and current during these processes.

Description

The apparatus consists of a capacitor connected in a circuit with a resistor and two meters—typically a voltmeter and an ammeter—to measure the voltage across the capacitor and the current in the circuit.

It includes terminals for connecting a DC power supply to charge the capacitor.

The charging cycle involves applying voltage to the capacitor, with the voltmeter measuring rising voltage as the capacitor accumulates charge, and the ammeter indicating the charging current which decreases over time.

During discharging, the power supply is disconnected, and the capacitor releases stored energy through the resistor, with voltage and current measured, showing an exponential decay behavior.

The apparatus allows observation of the time constant

τ=RC, characteristic of the resistor-capacitor combination.

This setup is essential for experiments demonstrating the principles of capacitor charge and discharge, including exponential voltage and current changes, foundational in electronics and physics education.
