Given a battery, three light bulbs, wire, and a compass, develop an experiment that shows evidence that magnetic field increases with current through the wire.

Expert Solution

Conclusion-In first case when three bulbs are present the resistance of circuit is large so current is minimum and hence deflection is small.In second case when two bulbs are present then current is more than previous case and deflection is more.In third case when only one bulb is present then current is maximum and hence deflection is also maximum .so we can say that as current increases the magnetic field also increases.

When we connect a number of light bulbs in a circuit with a battery, we can use our models of current, resistance, and Kirchhoff's principles to predict the relative brightness of the bulbs. If the bulbs are all identical, then the brightness of a bulb will be an indicator of the current through that bulb (i.e., a brighter bulb has more current). 1. The bulbs in the circuit shown on the right are all identical. Predict which bulb or bulbs...

Your lab partner builds a circuit with a single battery, three identical bulbs, and a single switch. You can see the bulbs but not the wiring of the circuit. With the switch closed, bulbs A and B are equally bright, and bulb C is not lit at all. When the switch is opened, the brightness of bulb A does not change, the brightness of bulb B decreases, and bulb C "turns on". Now (with the switch open), bulb A is...
