Ohm's Law Flashcards
1
Q
What must exist between two points for charge to flow?
A
A conductor
2
Q
What are resistors?
A
Conductors that resist the flow of charge are called resistors.
3
Q
State Ohm’s Law.
A
Current through a conductor is directly proportional to the potential difference across the conductor at a constant temperature.
4
Q
What factors affect resistance? (3)
A
- Temperature
- Thickness of the wire
- Length of the wire
5
Q

6
Q
Ohm definition.
A
A conductor has a resistance of one ohm if the current is one ampere when a potential difference of one volt is maintained between it’s ends.
