In this trainer you will measure the unknown values of Capacitance, in terms of two non-inductive resistance. The balance of bridge can be observed using a built-in audio amplifier with loudspeaker arrangement. This acts as a null detector. This bridge has the capability to measure unknown capacitance in the range of
Cx = C1 (R4/ R3)

Cx = capacitor whose capacitance is to be measured
C1 = a standard capacitor this capacitor is either an air or gas capacitor and Hence is loss free. However, if necessary, a correction may be made for the loss angle of this capacitor. R3 is a non-inductive resistor with multiple range of selection. R4 is a variable non- inductive resistor. The balance of bridge can be observed using a built-in audio amplifier with loudspeaker arrangement. This acts as a null detector.
