Electrical Exam Term
Ohm's Law
The fundamental electrical formula stating that voltage (V) equals current (I) multiplied by resistance (R): V = I × R.
Detailed Explanation
Ohm's Law is the most important formula in electrical work. Its three forms are: V = I × R (find voltage), I = V / R (find current), and R = V / I (find resistance). Combined with the power formula (P = V × I), it enables electricians to calculate any electrical quantity when two others are known. These calculations are essential for the C-10 exam and daily electrical work.
