Components:
- Resistor: A resistor is a passive electronic component having two terminals. It produces a voltage across its terminal which is proportional to the electric current passing through it in accordance with Ohm's law.
- Lamp: A lamp is a replaceable component such as an incandescent light bulb. It is designed to produce light from electricity. These components usually have a base of ceramic, metal, glass or plastic, which makes an electrical connection in the socket of a light fixture.
- Wire: A wire is a single, usually cylindrical, elongated string of metal. Wires are used to bear mechanical loads and to carry electricity and telecommunication signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate.
- Switch: A switch is an electrical component. It can break an electrical circuit by interrupting the current or diverting it from one conductor to another.
- Battery: A battery or voltaic cell is a combination of many electrochemical galvanic cells of identical type. Battery stores chemical energy .It can deliver higher voltage or higher current compared to single cells.
- Voltmeter: A voltmeter measures the electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by making use of an analog to digital converter.
- Ammeter: An ammeter is a measuring instrument .It measures the electric current in a circuit. Electric current is measured in amperes (A), hence the name.
- Non-contact ammeter: It is a type of ammeter that need not be a part of the circuit.
Procedure:
- Select the components from the right side of the simulator and connect them as in figure .1.
- Black color appears at the end of the wires when the connection is complete.
- Choose values for resistor, capacitor ,inductor and Battery.
- Find out the resonance frequency using the equation.
- Vary the frequency of A.C Power source below and above resonant frequency of the circuit and measure the current at each frequency using a non-contact ammeter
- Plot graph by taking frequency along X-axis and current along Y-axis.
