Ohm's law states:
AV = I/R
BV = I² R
CV = IR (voltage across a resistor = current × resistance)
DV = R/I
Answer & Solution
Correct answer: C. V = IR (voltage across a resistor = current × resistance)
Ohm's law: V = IR. Linear relation for ohmic resistors. SI units: V in volts, I in amperes, R in ohms (Ω). Power dissipated: P = VI = I²R = V²/R.
