| Maxwell’s Inductance Bridge ‘PSAW’
(1022 A) |
| We can also measure self inductance with the help of this bridge.
| P= |
R3 = |
consists of standard decade dial of 3 dials - 10 x 10, 100 x 10 & 1000 x 10 ohms. |
| Q = |
R4 = |
consists of standard decade dial of 3 dials - 10 x 10, 100 x 10 & 1000 x 10 ohms. |
| |
R2 = |
consists of standard decade dial of 3 dials - 0.01 x 10, 0.1 x 10 & 1 x 10 ohms. |
| |
L1 = |
single dial inductance box (10 mH to 100 mH) is to be connected from outside. |
| |
R2 = |
is connected in series with L1 to form third arm denoted as R. |
| |
L2 = |
unknown inductance whose value is to be calculated is connected in the fourth arm S. Schering Bridge |
| P = |
R1 = |
consists of ratio dial 1, 10, 100 & 1000 ohms. |
| |
R2 = |
consists of ratio dial of 1, 10, 100 & 1000 ohms. |
| |
C2 = |
Gang capacitor of 500 pf. |
| |
Q = |
In this arm C2 is placed in parallel with R2 to form second arm cd. |
| R = |
C3 = |
consists of three dial condenser box of 0.001 x 10, 0.01 x 10 & 0.1 x 10 mfd. |
| |
r = |
consists of three dial resistance box of 1 x 10, 10 x 10, 100 x 10 ohms. |
Unknown capacitor C1 whose value is to be calculated is connected in series with r to form fourth arm S.
Terminals for the connection of headphone, unknown capacitor and oscillator are also provided on the panel.
Supplied without headphone and oscillator. |
