Question

Write an activity to prove that the current drawn from the battery is equal to the sum of individual currents drawn by the bulbs. 

(OR) 

Prove that during parallel connection the current is distributed among the resistances by using an experimental activity.

Answer 1

Aim: 

To prove that the current drawn from the battery is equal to the sum of individual currents drawn by the bulbs. 

Materials required : 

1. Bulbs 

2. Ammeters 

3. Buttery 

4. Key 

5. Wires

Procedure : 

1. Connect the bulbs in parallel connection as shown in the given circuit. 

2. Measure the voltage across each bulb using a voltmeter or multimeter. 

3. Note these values in your notebook. 

Observation :

1. The voltage at the ends of each bulb is the same. 

2. Measure electric currents flowing through each bulb using ammeters. Note these values. 

3. Measure the current (I) drawn from the battery using the ammeter 1. 

Result (Conclusion) : 

The current drawn from the battery is equal to the sum of individual currents drawn by the bulbs.
