| Description | ||||||||||||||||||||||||||||||
| In this activity, you will study the growth of current in a circuit with an inductor. You will verify the energy stored in the inductor that carries a current.
In Experiment 1, you will compare the difference between using an ordinary resistor and a induction coil in a circuit.
In Experiment 2, you will study the magnetic energy stored in a coil with the aid of a neon bulb. In the first part, you will find the necessary voltage to cause a flash in the bulb. In the second part, you will connect the same bulb to the circuit with a coil at very low voltage.
In Experiment 3, you will study the problem of an ordinary switch when the circuit consists of an induction coil. Then, you will study how the problem can be solved.
In Experiment 4, you will compare the behaviour of two galvanometers, one being in series with a resistor and the other with an inductor. The frequency of the circuit is set very low so that you can trace the motions of the meter pointers.
In Experiment 5, you will connect an induction coil in series with a light bulb in an a.c. circuit. You will study the power output of the light bulb with and without the C-cores and the frequency response of the inductor. |
