The ETB-144 trainer is designed to study the behavior of a Resistor-Capacitor (R.C.) circuit when subjected to an ultra low frequency (ULF) AC source. This model helps learners explore phase difference, voltage drop across R and C, and vector relationships in a fundamental AC circuit.
The trainer includes a built-in ULF AC generator, regulated power supply, and 3 centre-zero analog meters for precise observation of current and voltages in the circuit. It is ideal for understanding transient and steady-state behavior in R-C circuits in electrical and electronics labs.
Key Features:
Demonstrates AC behavior of R-C circuits at ultra low frequency
Built-in ULF signal source and regulated power supply
Includes 3 centre-zero meters to measure voltages and current
Ideal for analyzing phase shift and impedance characteristics
Compact and educational design for lab use
Useful in basic electronics, AC circuit theory, and instrumentation labs
