Electric Circuit Components Quiz

Electric Circuits

• The main function of an ammeter in an electric circuit is to measure electric current.

Voltmeter Connection

• A voltmeter is typically connected in parallel in an electric circuit.

Work Done in a Conductor

• One joule of work is done when carrying one coulomb of charge from one point to another in a current-carrying conductor.

Resistors in Parallel

• The total effective resistance of resistors connected in parallel is less than the individual resistances.

Series Connection Failure

• If any component fails to work in a series connection, the entire circuit fails to work.

Series Connection Limitations

• A bulb and a heater cannot be connected in series because they have different current requirements.

Energy Conversion

• The internal resistance of the battery converts the rest of the energy from a battery into heat in an electric circuit.

SI Unit of Electrical Energy

• The SI unit of electrical energy is the joule (J).

Ammeter Connection

• When measuring electric current, an ammeter should be connected in series in the circuit.

Voltage and Resistance

• If the resistance decreases, the voltage across a resistor increases.

Power Formula

• The formula P = VI represents the relationship between power (P), voltage (V), and current (I) in an electric circuit.
