ETB-111 – Study of LR Circuit with a Source of Alternating EMF with Power Supply is a specialized training module designed to help students analyze the behavior of an inductor-resistor (LR) series circuit under alternating current (AC) excitation. This model allows observation of phase difference, impedance, and power factor in a simple LR circuit powered by a built-in AC source.
Ideal for foundational experiments in electrical and physics labs, it provides insight into the dynamic behavior of inductive elements and their impact on alternating current flow.
Key Features:
Demonstrates LR series circuit behavior under AC excitation
Built-in alternating EMF (AC) source and regulated power supply
Observation of voltage, current, and phase relationships
Study of impedance, reactance, and power factor in AC circuits
Clearly marked terminals and test points for easy measurements
Suitable for oscilloscope-based waveform observation
Ideal for basic electrical engineering and physics laboratory experiments
