| What symbol represents volts? | A capital V.
🗑
|
||||
| What is voltage also known as? | Electrical potential, or electromotive force.
🗑
|

| What is the rate of flow of electrons through a conductor? | Current
🗑
|
||||
| What is a ampere? | A measure of current, in which an ampere is defined as one coulomb of electrical charge flowing past a point in one second.

| With what tool is current measured? | Using an ammeter
🗑
|
||||
| What is a coulomb? | The fundamental unit of electrical charge. equal to the quantity of electricity conveyed in one second by a current of one ampere.
🗑
|
||||
| What are the two types of electrical current? | Direct current and alternating current.
🗑
|
||||
| What is direct current? | Direct current (DC) means that current only flows one way in a conductor.
🗑
|
||||
| What is alternating current? | Alternating current (AC) is when the current flowing in a conductor changes direction (moves back and forth) many times in a second.
🗑
|
||||
| In North America, alternating current is always delivered at...? | 60 cycles per second. (Or 60 hertz)
🗑
