RLC Phase Relationship on Scope

# 5L20.10

Description An RLC circuit has been constructed with linear isolation transformers to eliminate grounding when the circuit is attached to two two-trace oscilloscope. Using this device, the signals across the input, R, L, and C can be viewed simultaneously as the oscillator frequency is swept through resonance.

The device work well over 10KHz.
Resonance frequency is about 16KHz.
The phase of signal cross the L is little smaller than 90 degree because of non-pure of inductance.
