Question 1
1.
There is a relationship between the three measurable parts of an electrical circuit, which are
current, voltage and resistance.
electron, proton and neutron.
light bulb, battery and plug.
series, simple and parallel.
Question 2
2.
In a circuit, a source of voltage
converts electrical energy to heat.
impedes the flow of electricity through the circuit.
leaves the circuit open so that current does not flow.
provides the power to move charge through the circuit.
Question 3
3.
Which of these is an example of a resistor?
a battery, which has a positive and negative terminal
a light bulb that impedes the flow of electricity
an electrical charge moving at a constant rate
a conductive path that forms a closed loop
Question 4
4.
We measure __________ in amperes.
Question 5
5.
An ohm is a measure of
static.
voltage.
current.
resistance.
Question 6
6.
When not part of a circuit, what happens in a battery’s negative terminal?
The negative charge is attracted to the opposite charge in the positive terminal but cannot get there.
The negative charge travels directly across the battery to the opposite charge where it remains.
The negative terminal has no electrical charge.
The negative terminal has a positive charge.
Question 7
7.
In a series circuit, which of these is true?
There are exactly three resistors.
Voltage is shared across all resistors.
One resistor may burn out without affecting the other resistors.
There is more than one conductive path for the current to take.
Question 8
8.
In a parallel circuit with identical light bulbs, which of these is true?
A battery is not the source of voltage.
There is only one resistor, such as a light bulb.
The circuit is left open so that current cannot flow.
Adding more identical light bulbs will not change their brightness.
Question 9
9.
If everything else is equal, bulbs in a parallel circuit will burn brighter than bulbs in a series circuit.
True
False
Question 10
10.
If everything else is equal, increasing the ________ will decrease the ________ in a circuit.
current, voltage
voltage, current
brightness, heat
resistance, current
