Understanding Ohm's Law and Current Flow

What is the current in a circuit with a 12V battery and a 3 Ohm resistor?

• 6 amps

• 2 amps

• 3 amps

• 4 amps

If the voltage is doubled in a circuit with a 3 Ohm resistor, what happens to the current?

• It triples

• It doubles

• It remains the same

• It halves

When the current increases from 4 amps to 8 amps due to increased voltage, what could be happening?

• Same number of electrons flow at twice the speed

• Twice the number of electrons flow at half the speed

• Same number of electrons flow at half the speed

• Twice the number of electrons flow at the same speed

How is current defined in terms of charge and time?

• Current is the product of charge and time

• Current is the difference between charge and time

• Current is the ratio of charge to time

• Current is the sum of charge and time

What does a current of 4 amps represent?

• 4 coulombs per minute

• 4 coulombs per second

• 8 coulombs per second

• 8 coulombs per minute

What happens to the current if the resistance is halved while keeping the voltage constant?

• It remains the same

• It triples

• It halves

• It doubles

In a circuit where resistance is reduced, what could be happening to the electron flow?

• Twice the number of electrons flow at half the speed

• Twice the number of electrons flow at the same speed

• Same number of electrons flow at half the speed

• Same number of electrons flow at twice the speed

What is the effect of reducing resistance on the speed of electron flow?

• Electrons flow faster

• Electrons flow slower

• Electrons flow at the same speed

• Electrons stop flowing

What is the main question posed about electron flow when current is doubled?

• Do electrons flow at twice the speed?

• Do electrons flow at half the speed?

• Do twice the number of electrons flow at the same speed?

• Do electrons stop flowing?
