Question

Compute the voltage required between
terminal a-b so that a voltage
drop of 45 V_'occurs across 15

Resistors.
​

Answer 1

Answer:

Calculate voltage drop

Volts= Length x Current x 0.017. Area.

Volts= Voltage drop. Length= Total Length of wire in metres (including any earth return wire). Current= Current (amps) through wire. ...

Notes.

Example.

50 x 20 x 0.017= 17. Divide this by 4 (cross section area of wire): 17/4= 4.25V.
