engineering recuitment NHPC JE & THDC JE 2023 Mock Test Electrical and Electronics Measurements Measurement of R/L/C Using Bridge Circuits
The resistance and inductance of an inductive coil are measured using an AC bridge as shown in the figure. The bridge is to be balanced by varying the impedance Z2.
For obtaining balance, Z2 should consist of element(s):
1
R and C
2
R and L
3
L and C
4
Only C
