Resistance Formulas Flashcards
State the three formulas used to find R
1
Q
R = Resistance = Ohms
State the formula used to find resistance…
When volts and amperage are known.
R =
A
R = V / I
2
Q
R = Resistance = Ohms
State the formula used to find resistance…
When volts and power are known.
R =
A
R = V² / P
3
Q
R = Resistance = Ohms
State the formula used to find resistance…
When power and amperage are known.
R =
A
R = P / I²
