parallel circuit

Magnetism and Electricity I-Check 3
Study Guide
Electricity flows from the negative terminal of the D-cell to another
component (motor, light, buzzer) then into the positive terminal of the
In the first box- draw wires to connect the motor and the bulb in a
series circuit (a circuit with one pathway for electricity to flow).
In the second box- draw wires to connect the motor and the bulb in a
parallel circuit (a circuit with two pathways or more than one
pathway for electricity to flow-components must be parallel to one
When you build a series circuit using two bulbs on
one D-cell, the bulbs are dim because both bulbs are
sharing the same pathway from the D-cell.
In a parallel circuit, each bulb has a direct path to
the D-cell (energy source), so both bulbs light
The switch in the circuit is open in the circuit.
If you closed the switch, nothing will happenthe motor will not run. The D-cells are
connected negative terminal to negative
terminal, so there is no flow of electricity.
D-cells cannot be oriented this way because it
stops the flow of electricity when the negative
terminals are facing one another.
Tell if these circuits are SERIES or PARALLEL.
Draw schematic diagrams of the circuits above.
Magnetic force (magnetic field) goes through thin materials allowing
two magnets to stick together.
The wires from the battery do not
connect to both contact points on
the bulb holder, so the electricity
can’t go through the bulb or the
Draw a schematic diagram of the circuit above.
Only objects that are iron or steel will stick to magnets. Iron or steel
magnets can pick up other iron or steel objects if they are touching a
magnet because they become a temporary magnet.
This system uses electric energy to
make a person’s voice louder.
