Electric Circuit Kits

The Electric Circuit Kits is a hands-on educational model designed to help students explore the fundamental concepts of electrical circuits. This apparatus allows users to test and compare the behaviour of bulbs in both series and parallel connections, using a multimeter to measure the voltage across each bulb. The unit includes a bulb board with holders for both circuit configurations, a 6V power supply, and removable bulbs to observe real-time changes when altering the circuit.

This model is ideal for students, hobbyists, and educators. It provides a clear and practical demonstration of electrical circuit behaviour.

Working Principle

The kit demonstrates how voltage and current behave in series and parallel circuits using bulbs:

1. Series Circuit:

   • All bulbs are connected end-to-end in a single path.
   • The same current flows through each bulb.
   • The total voltage of the power supply is divided among the bulbs.
   • If one bulb is removed or fails, the entire circuit breaks and no bulbs will light up.

2. Parallel Circuit:

   • All bulbs are connected across the same voltage source.
   • Each bulb receives the full voltage of the power supply.
   • The total current is divided among the bulbs.
   • If one bulb is removed or fails, the other bulbs remain lit.
