A Wide Range Capacitance‐Conductance Bridge

摘要: The bridge described has been developed for reasonably accurate measurement by direct balance of capacitance and conductance in the frequency range 50 c/sec. to 5 mc/sec., over most this is essentially reading two admittance components with negligible unbalance from lead effects or guard circuits unknown. These properties are realized using work others. first employs inductively coupled ratio arms minimize residual impedance circuits, second, a shifter wye network good high an linear reading. Design considerations limitations these discussed, as suitable test cells auxiliary equipment.
