Choke and Resonance Coil 110v - ES-2

Choke and Resonance Coil.

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: A) series and parallel circuits with various combinations of resistance, inductance and capacitance; B) series and parallel resonance; C) mechanical oscillation at resonance; D) voltage-current relationships with varying capacitance and inductance; E) power and power factor in ac circuits.

A built-in transformer powers the circuit at 24 volts. All the set-ups are made with panel-mounted switches in accordance with a table of directions on the front panel. 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 with an extensive family of plotted curves.

Available for 120 volts, 60 Hertz.

Dimensions: Length 66cm, Width 33cm, Height 50cm. Weight: 6kg.
