If a copper layer has to be deposited on a steel spoon by electroplating,where should the copper rod be connected?

The electric potential of a positively charged body is positive,and the electric potential of a negatively charged body is negative.

What is meant by equivalent resistance?

$(i)$ filament of electric bulb.
$(ii)$ wires for electrical transmission lines. Justify your answer in each case.
