Discuss the advantages and disadvantages of series circuits compared to parallel circuits. give an example of where each type of circuit could be used.

Advantage of series circuit :

1. allows all the components in the circuit to have same current flowing through them.

2. one switch is enough to turn off all the components in the circuit in series.

3. make the circuit small by using smaller length of wire.

Disadvantages of series circuit :

1. If one component becomes defective , it does not allow other components to operate, since they share same current.

2. all components can not have same voltage across them.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
