PARALLEL CIRCUIT

Materials

unipolar wire, one 4.5 V battery, three 4.5 V bulbs, one switch, some wire terminals, a plywood base

• WHAT IT IS: It is a circuit where a number of users are connected in parallel on the same system. The connected users are crossed by the same tension which is the voltage of the system. each user works independently from the others connected in parallel on the system The parallel circuit is made up of three bulbs powered by the same source.
  

The circuit in parallel is a circuit formed by 3 bulbs which take the energy power from the source.

HOW IT WAS MADE: we have connected one extremity of the thread of the switch and we have made some connections at T with the bulbs so that the circuit is never interrupted. After that we have connected the 2 extremities of the thread to the battery.

WHAT DOES IT SHOWS ?: If, for whatever reason you disconnect one of the bulbs, the others will stay lit, like in your home electric system.
