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
