Advertisements
Solution
The three advantages of ring system are:
(i) Length of wiring used is much less and so less costly, since a single ring feeds the whole house.
(ii) In case of short-circuit, only the fuse of that particular appliance blows off, diconnecting it from the electric circuit; while the circuits of other appliances remain unaffected.
