Determine unknown inductance
WebIt can be calculated from this equation: T= L/R Where: L = the inductance of the inductor in Henrys R = the total resistance in series with the Inductor, including its equivalent series resistance. The time constant is a measure of time. After 57, the inductor is passing its maximum current. WebQuestion: 4. The AC excited impedance bridge shown below is used to determine the unknown inductance, Lx, and the unknown resistance, Rx, by adjusting the variable capacitance, Cs, and the variable resistance, Rs .

WebIn this bridge, an inductance is measured by comparison with a standard variable capacitance. The connection is shown in Figure 1. [Fig 1: Circuit diagram for Maxwell's Bridge] Here, L = Unknown Inductance, R 4 = Effective resistance of unknown Inductance coil, R 1, R 2, R 3 = Known non inductive resistance, C 1 = Standard … WebJun 6, 2024 · The bridge uses the principle of null-deflection i.e., by balancing the impedances on the bridge arms. The equation obtained when the bridge is balanced (i.e., ratio of impedances are balanced) can be used to determine the unknown inductance connected to it. There are two types of Maxwell's bridges used to find unknown …
WebThe inductance value is represented as L and its unit is Henry. One Henry value is equivalent to the induced one volt by changing of current in one ampere per second in an inductance value. The inductance value is of two types. One is the mutual inductance and another one is self-inductance. Formula for Inductance
