A potential difference of 10 V is applied separately across three conductors M, N and O. The currents measured are 250 mA in M, 100 mA in N and 40 mA in O.
Answer the following.
(i) Express each current in amperes.
(ii) Calculate the resistance of each conductor.
(iii) (a) Rank the conductors in decreasing order of current.
(b) Rank the conductors in increasing order of resistance.
