Question

In a series circuit the current is constant throughout the electric circuit. Thus it is obviously

impracticable to connect an electric bulb and an electric heater in series, because they need

currents of widely different values to operate properly. Another major disadvantage of a series

circuit is that when one component fails the circuit is broken and none of the components works.

If you have used ‘fairy lights’ to decorate buildings on festivals, on marriage celebrations etc.,

you might have seen the electrician spending lot of time in trouble-locating and replacing the

‘dead’ bulb – each has to be tested to find which has fused or gone. On the other hand, a parallel

circuit divides the current through the electrical gadgets. The total resistance in a parallel circuit

is decreased. This is helpful particularly when each gadget has different resistance and requires

different current to operate properly.

What we can conclude from the given idea BY agree and disagree the statement in front of them.

a) Parallel connections are more efficient for circuit connections.

b) Given ideas tells us why we always use parallel connections in houses.


c) This also tells us why the end of the circuit connected in series has very less current.

Answer 1

Answer:

the answer is a) Parallel connections are more efficient for circuit connections.
