The ETB-254 Transient Analysis of RLC Circuit Trainer is designed to study the complete transient response of Resistor-Inductor-Capacitor (RLC) circuits. It allows the observation of underdamped, overdamped, and critically damped responses, helping students understand second-order differential systems. The trainer includes built-in DC and AC power supplies, switching mechanisms, and test terminals to monitor voltage and current across circuit elements. This equipment is essential for circuit theory education in electrical and electronics engineering labs.
