02 - Ohm's Law Flashcards
(7 cards)
1
Q
How do you calculate voltage?
A
Current x Resistance
2
Q
How do you calculate current?
A
Voltage/Resistance
3
Q
How to calculate resistance?
A
Voltage/Current
4
Q
What is the relationship between voltage and current?
A
Directly proportional. This means if you double the voltage you double the current
5
Q
What is the relationship between current and resistance?
A
Inversely proportional. This means if you increase the resistance the current will decrease.
6
Q
What is resistance?
A
It is the measure of how much a component restricts and reduces the flow of current.
7
Q
How can you calculate resistance with a graph?
A
Rise over run
