Circuit Board Senior
Product Code : EL-EAE-10293
Quick answer: The Circuit Board Senior is a 3 V DC practical board on which students build, control and measure simple circuits. Beyond the cell holder, bulb holder, fan and fuse, it adds a toggle switch, buzzer, rheostat and multimeter, so current can be varied and readings taken during the experiment. Lab Exports manufactures it in Delhi for schools and colleges.

How the board is used in teaching
The senior board takes circuit work a step beyond switching a bulb on and off. With the rheostat in series, students can dim the bulb or slow the fan and see that adding resistance reduces the current. The multimeter lets them measure the voltage across a component and the current through it, turning observations into readings that can be tabulated and compared.
Three kinds of output device, a bulb, a fan and a buzzer, show electrical energy converted to light, motion and sound. The fuse and toggle switch reinforce the ideas of protection and control that come up again in lessons on household wiring.
- Build a series loop of cell holder, toggle switch, rheostat and bulb holder.
- Set the multimeter to a suitable range and connect it across the bulb as a voltmeter, or in series as an ammeter.
- Move the rheostat slider and record the meter reading at each setting, noting the bulb brightness.
- Replace the bulb with the fan or buzzer and repeat to compare the devices.
