Circuit Task Cards 10/25

The circuit does not work. Which procedure

would most likely allow the bulbs to light?

• Close the switch

• Remove Wire 1

• Remove Wire 6

• Remove a battery

Answer explanation

In the given question, the circuit is not working, and the goal is to light the bulbs. Closing the switch will complete the circuit, allowing the current to flow and the bulbs to light up. Removing wires or batteries would not help in achieving this goal.

A lab team constructed a circuit using three different-colored light-emitting diodes (LEDs).

Which bulb will most likely light if Switch 3 is closed and the other switches are left open?

Answer explanation

This is a parallel circuit - you have to identify the paths and then trace them.

If the switch were opened, which bulbs would still light?

• Bulbs 1 and 3 only

• Bulb 2 only

• All three bulbs

• None of the bulbs

Answer explanation

When the switch is opened, the circuit becomes incomplete, and no current can flow through it. As a result, none of the bulbs will light up, as they require a continuous flow of current to function.

The circuit shown uses a battery to power a motor.

What form of energy is the motor primarily used for?

• sound

• mechanical

• light

• thermal

Answer explanation

The motor in the circuit primarily uses mechanical energy. When the battery powers the motor, it converts electrical energy into mechanical energy, which is used to perform work or motion. The other options, such as sound, light, and thermal energy, are not the primary forms of energy used by the motor.

In some circuits used for decorating, one burned-out bulb prevents the other bulbs from lighting. In other circuits, one burned-out bulb has no effect on other bulbs.

In which of these circuits will other bulbs light even if one bulb is burned out?

Answer explanation

Parallel circuits have multiple paths for electricity to flow through. Series circuits for electrical energy to flow.

How many bell(s) would ring if Wire X were

removed?

• 2 bells

• 0 bells

• 1 bell

• 3 bells

• 4 bells

Answer explanation

If Wire X were removed, 0 bells would ring. This is because the removal of Wire X would disconnect the circuit, preventing any bells from receiving the necessary electrical signal to ring. Therefore, none of the bells would be able to ring.

This circuit has four light-emitting diode (LED) lights. It also has a battery and a switch.

Which LEDs produce light when the switch is in the position shown?

Answer explanation

Parallel circuits have multiple paths - you must trace the path. If the switch is open it is broken and if it is closed it flows.

All the lightbulbs in this circuit are lit. Which would remain lit if Wire 5 were removed?

Answer explanation

Parallel circuits = multiple paths

Removed wires = broken
