alleryOhm's law states that the current I through a conductor is proportional to:
AResistance R of the wire
BVoltage V (constant T)
CLength L of the conductor
DPower dissipated by wire
Answer & Solution
Correct answer: B. Voltage V (constant T)
1. Ohm: I ∝ V at constant temperature.
2. Equivalently V = I R, with R the resistance.
3. R ITSELF depends on length, area, material — but at fixed T, R is constant for an ohmic conductor.
