| Question | Answer |
| What are two kinds of current? | alternating(AC) and Direct (DC) |
| A flow of electric charge that regularly reverses its direction | Alternating Current (AC) |
| Electric current that flows in only one direction | Direct Current (DC |
| A flow of electric charge that passes a location every second. | electric current |
| The unit of current | Ampere (A) |
| A material's opposition to the flow of electric current | Resistance |
| Unit for resistance | Ohms |
