WebFeb 22, 2024 · 1. We define current as change in charge per time through an area A, not in and out of a volume. If the charge is moving through this area you get a current as expected because you have a net flow. If equally much charge passes through from both sides, the current is zero and the net charge is not moving. Share. WebThe average electrical current I is the rate at which charge flows, I ave = Δ Q Δ t, 9.1. where Δ Q is the amount of net charge passing through a given cross-sectional area in … foreign travel advice philippines
