The Maxwell bridge measures an unknown inductance in terms of a known capacitance. The maxwell The Hay circuit is more convenient for measuring high-Q coils; Hay bridge for inductance measurements Wien Bridge.
Maxwell's Wien Bridge In the Maxwell's Wien Bridge the positive phase angle of the inductance may be compensated by the negative phase. A.C. BRIDGE S. very prompt slides pls email the ppt at [email protected]com. Such a network is known as Maxwell's Wien Parallel Bridge It is also a ratio bridge used mainly as the feedback network.
It is may be used for the measurement of the audio-frequency but it is not as accurate as the modern digital frequency meters, as shown in fig.
Connect with Facebook. The bridge circuit is shown in Fig In the simple theory of this bridge, capacitors C1 and C2 are assumed to be loss-free and resistances R1 and R2 are separate resistors.

Bridges are often used for the precision measurement of component values, like . () shows the circuit arrangement of Wien bridge under balance condition. Maxwell bridge can be used to measure inductance by comparison either with.
Instead of using a variable inductor in Maxwell Wien Bridge, we use a variable capacitor. Here we compensate for the positive phase angle of the inductive impedance AC Bridge and Theory of AC Bridge · Maxwell Bridge Construction and.
Maxwell-Wien Bridge. For example, the impedance of a series-connected resistor (R) and inductor (L) would be Mathematical analysis of the Maxwell-Wien bridge is as follows: Rx. Carefully measure and record all component values prior to circuit construction. 3 A.C. Bridges C A.C.

Bridges Resistances can be measured by direct-current Wheatstone bridge, shown in Fig a for which the condition of balance is that Inductances and capacitances can also be measured by a similar four-arm bridge, as shown in Fig b ; instead of using a source of direct current, alternating current is employed and galvanometer is replaced by a vibration galvanometer for commercial frequencies or by telephone detector if frequencies are higher to Hz.
