Series and Parallel Circuits

Why is it not necessary to measure the electric current flowing through each globe separately when two or three globes are connected in series?

• The current is different in each globe

• The current is the same throughout the series circuit

• The globes affect the current differently

• The current only flows through the first globe

What happens to the brightness of the globes as more globes are added in series?

• The brightness increases

• The brightness remains the same

• The brightness decreases

• Only the first globe gets brighter

What happens to the current in a circuit as more globes are added in series?

• The current increases

• The current remains the same

• The current decreases

• Depends on the type of globe added

If one light in a series circuit breaks, what happens to the other lights?

• They become brighter

• They remain lit

• They all go out

• Only the adjacent light goes out

In a parallel circuit with two globes, what is the relationship between the total current and the current through each globe?

• The total current is less than the sum of individual currents

• The total current is greater than the sum of individual currents

• The total current is equal to the sum of individual currents

• There is no relationship between the currents

How does the voltage drop across globe 1 compare with the voltage drop across globe 2 & 3 in a parallel circuit?

• The voltage drop across lamp 1 is greater

• The voltage drop across lamp 1 is less

• The voltage drops are equal across all 3 lamps

• It depends on which lamp was connected first

If one light in a parallel circuit breaks, what happens to the other lights?

• They all go out

• They become dimmer

• They become brighter

• They remain lit with the same brightness

What is a general statement about voltage drops across light globes connected in parallel?

• The voltage drops are always different

• The voltage drops are equal to the power supply voltage

• The voltage drops add up to the power supply voltage

• The voltage drops depend on the order of connection

How does adding a second globe in parallel affect the brightness of the first globe?

• The first globe becomes brighter

• The first globe becomes dimmer

• The first globe's brightness remains the same

• The first globe flickers

How does adding a second globe in parallel affect the brightness of the first globe?

• The first globe becomes brighter

• The first globe becomes dimmer

• The first globe's brightness remains the same

• The first globe flickers
