Maxwell Inductance Capacitance Bridge
Product Code : JA-SI-8074
The Maxwell Inductance Capacitance Bridge (SKU JA-SI-8074) measures an unknown inductance in terms of a standard capacitance, a classic AC bridge practical in college physics and electrical engineering. The unit carries its own 1 kHz sine-wave source with an indicating lamp, a null detector with digital display, and the circuit laid out on the board with 4 mm sockets, so students wire the bridge, adjust the decade dials to a null and calculate the inductance.
