ES-2 Choke & Resonance Coil


SKU: N/A Category:


This is a unique piece of student equipment for studying the basic elements of electrical circuits — resistance, inductance, and capacitance.

Some of the circuit arrangements which can be investigated are:

  1. series and parallel circuits with various combinations of resistance, inductance and capacitance;
  2. series and parallel resonance;
  3. mechanical oscillation at resonance;
  4. voltage-current relationships with varying capacitance and inductance;
  5. power and power factor in ac circuits.

All the set-ups are made with panel-mounted switches in accordance with a table of directions on the front panel.

A built-in transformer powers the circuit at 24 volts.

Jacks are provided for voltmeter and ammeter connections.

The magnetic core of the inductor has a metric scale so that curves may be plotted.

The instruction manual contains complete directions for all demonstrations along with an extensive family of plotted curves.
