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.

Three identical light bulbs are connected to a 30V battery in a circuit. Bulb A is on main loop and closest to battery. Bulbs B and C are in parallel and the junction is after Bulb A S1 is in the loop with bulb B and S2 is in loop with bulb C Initially switch 1 is closed and switch 2 is opened. When switch 2 is closed what happens to the brightness of bulbs A,B and C Please explain

A circuit for light bulbs in a car has a battery with a terminal voltage of 24.5 V. The internal resistance of this battery is 0.66 Ohms. All bulbs have the same efficiency. The first bulb of this circuit has 15 Ohms and is in series with the battery. After this there are two branches. One branch has the third bulb with 5 Ohms and the fourth bulb with 7 Ohms. The third and fourth bulbs are in series with...

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...

Draw a series circuit with a battery, wires, and more than 3 light bulbs. You decide the features: the battery's voltage, the number of light bulbs, and the resistance in each light bulb. Answer the following questions regarding your circuit: 1. What is the voltage for each bulb? 2. What is the circuit's resistance? 3. What is the current at any point in the circuit? Send a picture of it please!

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...

1. What is the definition of electric current? 2. Explain how, given a battery, a light bulb, and two wires, you can cause the bulb to light. Draw a diagram. 3. What is the difference between a series circuit and a parallel circuit? 4. If you have a string of Christmas lights or non-denominational festive lights, how can you tell whether they're wired in series or parallel? 5. It takes only 0.1 Amps of current across your heart to kill...
