The radiation resistance of a circular loop of a turn is

Home » Electromagnetic Theory » Electromagnetic theory miscellaneous » Question

The radiation resistance of a circular loop of a turn is 0.01 Ω. The radiation resistance of five turns of such a loop will be—

1. 0.002 Ω
2. 0.01 Ω
3. 0.05 Ω
4. 0.25 Ω

Correct Option: C

Radiation resistance of loops of N turns is given by

R_r= 31200		N	A
			λ²

A → Area of the loop
