I have a resistance coil of 3 om with me. But I do not know how to put it to use. Please tell me how does it work? Is there any difference between resistor and resistance coil?

Expert Answer:

No, a resistance coil and resistor is the same thing. You know the resistance of the coil i.e. 3 ohms. A possible use of the resistor coil is to just construct an electric circuit by connecting the resistor to a battery source (AA batteries or bigger ones) and a detector like small bulb. The bulb would light up when the circuit would be completed. Also, by changing voltage of the power sources, you can play around with the brightness of the bulb. Furthermore, if you have an ammeter, then you can actually measure the actual current flowing through the circuit in the presence and absence of the resistor.
