Completion
Complete each statement.
9. When electrical charge moves continuously in one direction through a conductor, it’s called ​Direct
(DC)​ current.
10. When electrical charge moves back and forth through a conductor, it’s called ​Alternating (AC)
current.
11. The most common type of a DC voltage source is a ​battery​.
12. When frequency and hertz are used to describe electrical current, they are describing ​AC (alternating
current) ​voltage.
13. Identify the numbered parts in the electrical circuit shown.
1​ a.
4​ b.
2​ c.
3​ d.
Voltage Source
Switch
Conductor
Load
14. Voltage acts like a force, because it moves ​electrons (electricity) ​ through a circuit.
15. When we are talking about electron charges, we say that unlike charges ​attract​ each other and like
charges ​repel​ each other.
16. Here are two types of electricity: direct current (DC) and alternating current (AC). The type of
electricity found in your typical flashlight battery is ​DC​.
17. When batteries are connected in series, the positive terminal of one battery should be connected to
the ​negative​ terminal of the other battery.
18. According to Ohm’s Law: How do you find: Voltage, Current, & Resistance?
V = IxR
I= V/R
R = V/I
