Match the following
The law that states that resistance in a circuit is equal to voltage divided by current.
Ohm's law
The measurement of how difficult it is for charges to flow through an object; measured in ohms (Ω).
resistance
An electric circuit in which all parts are connected one after another along one path.
series circuit
Match the following
The difference in electrical potential energy per charge between two places in a circuit; measured in volts (V).
voltage
A complete, unbroken path through which electric charges can flow.
electrical circuit
An electric circuit in which different parts of the circuit are on separate branches.
parallel circuit
Which of the following is NOT a main component of a circuit?

Which of the following describes an advantage of parallel circuits?
Each device shares the voltage.
If one device goes out, the others are unaffected.
Adding devices reduces the current.
More voltage is needed to reach an appropriate current.
In a circuit containing a switch, if the switch is turn "on"....
....the circuit is closed
....the circuit is open
....there is no current
....the voltage is increased
