Principle

Ohmic resistances, inductances and capacitances are determined in a Wheatstone bridge circuit operated on AC. Balancing is done aurally through headphones, using the high sensitivity of the human ear.

Benefits


Quickly obtain experiment results using the Wheatstone bridge

Easy to tune by aural measurement relying on the sensitivity of the human ear

Save time while switching the numerous coils, resistance and capacities on-the-fly
