What does Ohm's Law state?
Back
Voltage (V) = Current (I) x Resistance (R)
3.
FLASHCARD QUESTION
Front
How do you calculate Voltage using current and resistance?
Back
Voltage = Current x Resistance (V = I x R)
4.
FLASHCARD QUESTION
Front
What is the formula to find Resistance if Voltage and Current are known?
Back
Resistance = Voltage / Current (R = V / I)
