- Resistor: A resistor is a two-terminal electronic component that produces a voltage across its terminals that is proportional to the electric current flowing through it in accordance with Ohm's law.
- Lamp: A lamp is a replaceable component such as an incandescent light bulb, which 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 telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate.
- Switch: In electronics, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.
- Battery: In electronics, a battery or voltaic cell is a combination of many electrochemical Galvanic cells of identical type to store chemical energy and to deliver higher voltage or higher current than with single cells.
- Voltmeter: A voltmeter is an instrument used for measuring 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 use of an analog to digital converter.
- Ammeter: An ammeter is a measuring instrument used to measure the electric current in a circuit. Electric currents are measured in amperes (A), hence the name.
- Non-contact ammeter: A type of ammeter that need not be a part of the circuit.
- The components are given at the right side on the simulator. They can be dragged and the circuit can be formed as in the circuit diagram. The colour change in the nodes of the components confirms the connection. By noting the current and voltages through different branches the law can be verified.
