Charge effective formule
WebAt r ≈ 0, the positive charge experienced by an electron is approximately the full nuclear charge, or Z e f f ≈ Z. At intermediate values of r, the … WebConsider a capacitor of capacitance C, holding a charge + q on one plate and − q on the other. Moving a small element of charge d q from one plate to the other against the potential difference V = q/C requires the work d W : where W is the work measured in joules, q is the charge measured in coulombs and C is the capacitance, measured in farads.
