| See our and for details | It uses a combination of standard resistors and capacitors to "balance out" the inductor of unknown value in the opposite arm of the bridge: is adjustedsis adjusted to 120 nF and RsSuppose this bridge circuit balances when C to 14 |

| If the source frequency is 400 Hz, and the two fixed-value resistors are 1 of the inductor being tested |
Worksheet An AC bridge circuit commonly used to make precision measurements of inductors is the Maxwell-Wien bridge.
