C1. A single wire 4m above ground transports a current of 100 Ato a remote load. it is horizontally seperated from the currentcarrying the return current by 0.5 m.
a) sketch the system  Â
b) Starting with Amperes circuital law, derive an expression forthe field at any point p from one wire. State your assumptions.
c) using the formula derived in question C 1b calculate thefield 2m below the transmission line and at ground level,equidistant from both wires (ignoring any effects of theground)
