• Volt

What does the symbol 'V' represent in electrical terms?

• Voltage drop

• Current

• Voltage

• Resistance

How is electrical charge calculated in a circuit?

• Q = V × R

• Q = I × t

• Q = E / V

• Q = P × t

What is the relationship between voltage and energy transformed?

• Voltage has no effect on energy transformed.

• Energy transformed is independent of voltage.

• Energy transformed is inversely proportional to voltage.

• Energy transformed is directly proportional to voltage.

What is the unit of energy in a circuit?

• ohm

• joule

• watt

• volt

What does current measure in a circuit?

• Current measures the power consumed in a circuit.

• Current measures the flow of electric charge in a circuit.

• Current measures the resistance in a circuit.

• Current measures the voltage across a circuit.

What is the effect of increasing voltage on energy transformed?

• Increasing voltage decreases the energy transformed.

• Energy transformed is independent of voltage.

• Increasing voltage increases the energy transformed.

• Voltage has no effect on energy transformed.

What is the formula for calculating energy transformed?

• E = F × d

• E = m × c^2

• E = P × t

• E = I × R

What is the role of electrons in a circuit?

• Electrons are the source of voltage in a circuit.

• Electrons are used to insulate the circuit.

• Electrons are responsible for generating heat in a circuit.

• Electrons are the charge carriers that flow through a circuit, enabling the flow of electric current.

How does time affect the amount of electrical charge that moves in a circuit?

• Time has no effect on electrical charge in a circuit.

• Charge movement is independent of time in a circuit.

• Increasing time decreases the amount of charge that moves.

• Time affects the amount of electrical charge by increasing it proportionally with constant current.
