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   

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)
