Δϕ/Δt = ε = e = (iΔt)/R = QR. ⇒ Q = Δϕ/R.

1. Q = Δϕ/R
2. Q = Δϕ × R
3. Q = Δϕ/R²
4. Q = Δϕ × R²

Correct answer: Q = Δϕ/R

Solution

The equation Q = Δϕ/R is derived from the relationship between induced EMF (ε), resistance (R), and charge (Q). Using Ohm's law and Faraday's law, Q = Δϕ/R is correct.
