Electricity and Circuits

What is the difference between a series circuit and a parallel circuit?

• The circuits have different resistance

• The components are connected differently in each circuit.

• The circuits have the same components

• The circuits have different voltage

In a series circuit, what happens to the current as more resistors are added?

• The current stays the same

• The current increases

• The current becomes alternating

• The current decreases

In a parallel circuit, what happens to the current as more resistors are added?

• The total current increases

• The total current remains the same

• The total current becomes zero

• The total current decreases

What is the total resistance in a series circuit?

• Average of individual resistances

• Difference of individual resistances

• Sum of individual resistances

• Product of individual resistances

What is the total resistance in a parallel circuit?

• It is calculated using the formula R_total = R1 + R2 + R3 + ...

• The total resistance in a parallel circuit is always infinite

• It is calculated using the formula 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

How does the brightness of bulbs in a series circuit compare to the brightness of bulbs in a parallel circuit?

• The brightness of bulbs in a series circuit remains the same as the brightness of bulbs in a parallel circuit.

• The brightness of bulbs in a series circuit has no effect on the brightness of bulbs in a parallel circuit.

• The brightness of bulbs in a series circuit increases compared to the brightness of bulbs in a parallel circuit.

What happens to the voltage in a series circuit?

• It remains constant throughout the circuit.

• It is divided among the components.

• It increases as it goes through each component.

• It decreases as it goes through each component.

What happens to the voltage in a parallel circuit?

• Increases

What is the formula to calculate total resistance in a parallel circuit?

• 1/Rt = 1/R1 + 1/R2 + 1/R3 + ...

• Rt = R1 - R2 - R3 - ...
