The fall of potential per km is 8 volt and the average resistance per km is 0.5Ω. The power loss in the wire isA signal of 0.1 kW is transmitted in a cable. The attenuation of cable is –5 dB per km and cable length is 20 km. The power received at receiver is 10^–x W. The value of x is ...... [Gain in dB = 10 log10 (P0/Pi)]
