Why does current decrease when charging a capacitor?
Why does current decrease when charging a capacitor? Capacitor is like a bucket which is storing electrostatic energy , as a constant voltage or current is there to provide the energy . As the charge inside the capacitor increases exponentially more the current passing through the capacitor will decrease because it won’t allow any current […]
