Question

A quantity X = ε₀L(ΔV/Δt) where ε₀ is permittivity, L is length, ΔV/Δt is rate of change of voltage. X has the same dimensions as:
  1. A
    Charge
  2. B
    Current
    Correct
  3. C
    Resistance
  4. D
    Voltage

Correct answer

Current

Explanation

ε₀(ΔV/Δt) has dimensions of current density × length, and with factor L it gives current [A]. So X has dimensions of current.
