Determine Time Constant of RC Circuit | Charging & Discharging of Capacitor | Physics Experiment

In this video on Physics Concepts, we perform the Physics practical experiment to determine the time constant of an RC circuit by studying the charging and discharging of a capacitor through a resistor. The time constant (τ) of an RC circuit is given by the formula: τ = R × C, where R is resistance and C is capacitance. It represents the time taken by the capacitor to charge up to 63% of its maximum voltage or discharge to 37% of its initial voltage. 📚 Topics Covered in This Video • Introduction to RC Circuit • Charging of a Capacitor • Discharging of a Capacitor • Definition of Time Constant (τ) • Circuit Diagram Explanation • Graph of Voltage vs Time • Experimental Procedure • Observations and Calculations • Result and Precautions This experiment is very important for Class 12 Physics students, FSC practical exams, and viva questions. It helps in understanding capacitor behavior, exponential growth and decay, and time-dependent circuits.
