The portable lighting equipment for a mine is located away from its dc supply source needing 100 metres of connecting wire. The lighting equipment can be considered as a purely resistive load. The power lost in the connecting wire is 7% of the power supplied by the dc supply source. If this lighting equipment needs to be moved further away from the same dc supply source and now needs 200 metres of connecting wire (you can assume that the wire of the same material and cross-section as before is being used), then power lost in the connecting wire as a percentage of the power supplied by the de supply source (computed to one decimal place) now is given by (Note: do not include units in your answer, e. g.
