Electrical appliances are not connected in
series because
series circuit is complicated
power loss is more
appliances have different current ratings
none of the above
Electrical appliances are connected in
parallel because it
is a simple circuit
draws less current
results in reduced power loss
makes the operation of appliances
independent of each other
