Product Code : SCL-EELE-12243
Indian Lab Suppliers supplies the Measurement of Inductance and Capacitance by Maxwell's L/C Bridge with power supply and Oscillator (C.R.) (Product ID: 12243) as part of its electronics engineering lab equipment range. It is a self-contained Maxwell L/C bridge for finding the values of unknown inductors and capacitors.
Quick Answer
The bridge is driven by a built-in 1 kHz sine oscillator, and the null is detected by ear through an on-board audio amplifier and speaker. Five unknown capacitors and three unknown inductors are chosen with band switches, and two decade resistances in 100 Ω steps plus a potentiometer are adjusted for balance. For inductance, the balance gives L = R2R3C, so an inductor is measured against a known capacitance. A ±12 V DC, 100 mA IC-regulated supply is connected internally, and no other apparatus is needed.
