The battery voltage is divided in between the two lamps.Each lamp will certainly have fifty percent the battery voltage if the lamps room identical.

You are watching: When two lamps are connected in series to a battery


In parallel so that each component has actually the same voltage.

Both lamps have the full battery voltage throughout them.The battery present is divided in between the two lamps.

The terms series circuit and parallel circuit are periodically used,but just the simplest of circuits are completely one type or the other.It is much better to refer to certain components and say they room connected in series or connected in parallel.

For example: the circuit mirrors a resistor and LED connected in series(on the right) and two lamps associated in parallel (in the centre).The move is associated in collection with the two lamps.

See Lamps in Parallel below for an additional example.

A circuit through both seriesand parallel connections.

If several lamps are connected in series they will certainly all it is in switched on and off with each other by a switch connectedanywhere in the circuit. The it is provided voltage is divided equally in between the lamps (assuming they room all identical).If one desk lamp blows all the lamps will certainly go out due to the fact that the circuit is broken.


If several lamps are linked in parallel every one has the complete supply voltage across it.The lamps might be switched on and off independently by connecting a switch in collection witheach lamp as presented in the circuit diagram. This arrangement is provided to manage the lamps in buildings.

This type of circuit is often referred to as a parallel circuit but you can see the it isnot really so basic - the switches are in series with the lamps, and it is theseswitch and also lamp pairs that are connected in parallel.


If numerous on-off switches are associated in series they need to all it is in closed (on) to complete the circuit.

The diagram mirrors a basic circuit through two switches associated in collection to manage a lamp.

Switch S1 AND move S2 must be close up door to light the lamp.


If numerous on-off switches are connected in parallel just one requirements to it is in closed (on) to finish the circuit.

The diagram reflects a simple circuit through two switches linked in parallel to regulate a lamp.

Switch S1 OR switch S2 (or both that them) should be close up door to light the lamp.
