Basics of Electricity and Circuits Quiz

The SI unit of electric current is Amperes.

A resistor is a component in a circuit that restricts the flow of current.

The unit of electrical power is Watts.

Rubber is commonly used as an insulator in electrical wires.

The formula to calculate electrical power is P = V * I.

Kirchhoff's Current Law states that the total current entering a junction is equal to the total current leaving the junction.

Ohm's law states that the relationship between voltage, current, and resistance in an electrical circuit is V = I * R.

A capacitor is used to store electrical charge in a circuit.

The symbol for a resistor in an electrical circuit diagram is 'R'.

The purpose of a fuse in an electrical circuit is to protect against overcurrent.

In electricity, 'AC' stands for Alternating Current.

In a series circuit, the total resistance is equal to the sum of individual resistances.

'DC' in electrical circuits stands for Direct Current.

The purpose of a diode in a circuit is to control the flow of current.

The unit of electrical resistance is Ohms.

In a parallel circuit, the total resistance decreases as more resistors are added.

The primary function of a transformer in an electrical circuit is to step up or step down voltage.

The flow of electrical current in a conductor is due to the movement of electrons.

The SI unit of capacitance is Farad.

The primary function of a relay in an electrical circuit is to control the flow of current.

Kirchhoff's Voltage Law (KVL) is used to determine the total voltage in a closed loop circuit.

The resistance of a superconductor at very low temperatures is zero.

The unit of electric charge is Coulombs.

In a DC circuit, the voltage across a resistor connected in series remains constant, while the current varies.

The unit of magnetic flux is Weber.
