The

resistance of the loop is less by the factor 2.5 × 10−" or about 2.2 X 10-" ohm.

The

**radiation**resistance of the wire is 790/(300) * = 0.88 × 10-2 ohm. Theresistance of the loop is less by the factor 2.5 × 10−" or about 2.2 X 10-" ohm.

Hence it is obvious that the

**radiation**contribution to the resistance of ordinarycoils can be ...
