单词	Campbell bridge
释义	Campbell bridge Electronics and Electrical Engineering An a.c. bridge that is used to measure a mutual inductance, M, by comparison with a standard capacitance, C. The resistances R₁ and R₂ are varied until null deflection is obtained on the indicating instrument I (see diagram). At balance $\frac{L}{M} = \frac{(R + R_{1})}{R}$ $\frac{M}{C} = R R_{2}$ where L is the self-inductance of the coil AB. Campbell bridge
