A uniformly-loaded D.C. distributor is fed at both ends with equal voltages. As compared to a similar distributor fed at one end only, the drop at the middle point is
Right Answer is:
One-fourth
SOLUTION
- When distributed is fed at one end only, the voltage drop at the middle point is =IR/2.
- When distributed is fed at both ends with equal voltages, the voltage drop at the middle point is = IR/8.
- Where I is the current fed to the distributor R is the total resistance of the distributor.
- Therefore, a uniformly loaded DC distributor is fed at both ends with equal voltages the drop at the middle point is one fourth as compared to a similar distributor fed at one end only.
