Q current

Q’ current is torque producing current – in torque mode, ‘D’ is commanded to be zero and ‘q’ is commanded to be the necessary current to produce the desired . Electric charge is the physical property of matter that causes it to experience a force when. I is the net outward current through a closed surface and Q is the electric charge contained within the volume defined by the surface. GCSE PHYSICS – Electricity – What is Current? A coulomb is a unit of charge, so an electric current is a flow of charge.

The momentary current is given by the derivative of the electric charge by time. The instantaneous current, i(t), at any . A = C s-) Current is measured in a circuit using an ammeter which is placed in series with the component of interest in the circuit.
