मैक्सवेल - प्रेरकत्व - धारिता ब्रिज में 

Z1Z4 = Z2Z3

जहाँ Z1, Z2, Z3, Z4 प्रतिबाधाएं हैं

दिया हुआ:

R2 = 1000 Ω,

R3 = 1000 Ω,

R4 = R5 = 2000 Ω,

C5 = C4 = 1 μF

तो ब्रिज संतुलन के लिए,

\(\frac{{{L_x}}}{{{C_5}}} = {R_2}{R_3}\)

Lx = R2R3C5

Lx = 1000 × 1000 × 1 μ = 1 H

साथ ही Rके लिए,

अर्थात RxR5 = R2R3

\({R_x} = \frac{{{R_2}{R_3}}}{{{R_5}}}\)

\({R_x} = \frac{{1000\; \times \;1000}}{{2000}} = 500\;{\rm{\Omega }}\)

तो Lx = 1H, Rx = 500 Ω
