Product Code : SCL-EELE-12115
Indian Lab Suppliers supplies the Study of the Frequency Response & Phase Relation in a Series LCR Circuit (Product ID: 12115) as part of its electronics engineering lab equipment range. It is a self-contained board for plotting the frequency response of a series LCR circuit and studying the phase relation between its voltage and current.
Quick Answer
As the frequency of the built-in 50 Hz–1 kHz sine oscillator is swept, the current in the series LCR circuit rises to a peak at resonance, where inductive and capacitive reactances cancel; below resonance the current leads the voltage and above it the current lags. A transformer with 10, 20 and 30 V AC taps (100 mA) supplies the circuit at mains frequency, and 3½-digit digital AC meters read voltage (200 V range) and current. The current meter range is listed as 200 µA, so please confirm it at quotation. It runs on 230 V ±10%, 50 Hz and comes with six 4 mm patch cords.

Frequently Asked Questions
What happens at resonance?
Inductive and capacitive reactances cancel, so current is at its maximum and in phase with the voltage.
What frequency range does the oscillator cover?
50 Hz to 1 kHz.
Which AC voltages are available?
10, 20 and 30 V AC from the transformer taps.
