Establish the general formula for effective capacitance C for parallel combination of n capacitor.

Establish the general formula for effective capacitance of a series combination of n capacitors.

n identical capacitors are connected in parallel. Find their equivalent capacitance.

A charged capacitor is connected to an inductor at an instant of time t=0.If the capacitor and the inductor are taken to be pure, write down the equation of effective potential difference across the combination at any instant of time t and solve it for instantaneous current through I the combination.Explain brefly the exchange of electric and magnetic energy between the capacitor and the inductor.
