Lamps in Parallel Kit
Product Code : SCL-EAE-11194
Quick answer: The Lamps in Parallel Kit is a baseboard circuit with three MES lamp holders wired in parallel, each branch with its own switch, and an on-board 0-6 V DC voltmeter. Students use it to show that every parallel branch receives the same voltage and that one open branch leaves the other lamps lit. It runs on 3-6 V DC. Lab Exports manufactures it in Delhi for schools and colleges.

How the parallel circuit experiment is done
In a parallel circuit each lamp is connected directly across the supply, so every branch receives the full supply voltage and the total current is the sum of the branch currents, I = I1 + I2 + I3. Because each branch is a separate path, switching off or removing one lamp does not affect the others.
- Fit the three MES bulbs and connect the battery holder or a 3-6 V DC supply to the board.
- Close one branch switch, read the voltmeter and note the brightness of the lamp.
- Close the second and third switches in turn, reading the voltmeter each time.
- Open any one switch and observe that the remaining lamps stay lit.
The voltmeter reading stays practically the same as branches are added and the lamps keep equal brightness. This is the opposite of a series circuit, where adding lamps makes each one dimmer, which is why household wiring connects appliances in parallel.
