Electricity Quiz

What is electric charge?

• The energy that moves electrons.

• A property that makes electrons and protons attract or repel each other.

• The force that pushes current in a circuit.

• The resistance to current flow.

What type of electrical current flows in only one direction?

• Alternating Current (AC).

• Direct Current (DC).

• Steady Current.

• Periodic Current.

Choose the correct statement:

• Alternating current changes direction periodically.

• Direct current changes direction periodically.

• Alternating current never changes.

• Direct current is used in homes.

What is voltage?

• The force that pushes charges to move in a circuit.

• The amount of charges in a circuit.

• The resistance to current flow.

• The amount of energy lost in a circuit.

What is the unit of measurement for voltage?

• Ampere.

• Volt.

• Ohm.

• Watt.

True or False: "Resistance reduces the flow of electric current."

• True.

• False.

What is the relationship between voltage, current, and resistance according to Ohm's Law?

• Current = Voltage × Resistance.

• Current = Voltage ÷ Resistance.

• Voltage = Resistance ÷ Current.

• Voltage = Current × Resistance.

What happens when resistance increases in an electrical circuit?

• Current increases.

• Current decreases.

• Current stays the same.

• Voltage is unaffected.

What does Kirchhoff's Current Law state?

• The sum of voltages in a closed loop is equal to the sum of all voltage rises in that loop.

• The total current entering a junction is equal to the total current leaving the junction.

• The amount of energy consumed in the circuit.

• The output voltage of a power source.

Which law describes the relationship between power, voltage, and current?

• Ohm's Law.

• Power Law.

• Kirchhoff's Voltage Law.

• Kirchhoff's Current Law.
