Parallel Circuits Quiz

What is the flow of electrons in a circuit?

• From positive to negative

• From negative to positive

• From left to right

• From right to left

What happens to a series circuit when one bulb breaks?

• The circuit continues to work

• The circuit stops working

• The brightness of the bulbs increases

• The voltage of the battery decreases

What is the advantage of wiring lamps in parallel?

• They provide more voltage

• They increase the resistance

• They decrease the current

• They provide multiple paths for current

What is the voltage in a parallel circuit?

• It varies depending on the component

• It is always zero

• It is the same going into each branch

• It is the sum of the voltages in each branch

How do you calculate the total current in a parallel circuit?

• By adding the currents in each branch

• By multiplying the currents in each branch

• By dividing the currents in each branch

• By subtracting the currents in each branch

What is the formula for calculating total resistance in a parallel circuit?

• RT = R1 + R2

• RT = 1 / (1/R1 + 1/R2)

• RT = R1 * R2

• RT = R1 / R2
