An electrical circuit must be complete i.e it must form a closed loop,for it to work. Current only flow if the circuit is complete. A complete circuit is one that consist of a Voltage source, a consumer like a bulb and conductors. The conductor then connects the consumer and the voltage source together forming a closed loop.
The load that is connected in a circuit is what does the work in the circuit.
Electricity travels in a closed circuit when it does work.
Electricity travels in a closed circuit when it does work.
A seríes circuit will not work when a component burns out, because then no current can pass around the circuit.
A parallel circuit.
No
yes it does have to be a closed circuit
No.
Not always. Depends on the circuit.
because the circuit is not a full circuit so it wont work!
A series circuit will work if there is a closed path through which the current can pass, and a voltage source. Otherwise it won't.
why would a circuit not work when a wire is replaced with a cotton string
