Find potential difference after switch, S is closed?

Name the quantity for which the potential difference of a cell becomes less than its emf due to its internal resistance.

A 2muF capacitor is charged to a potential of 20V. Another 3muF uncharged capacitor is connected in parallel with the first capacitor. What would be the terminal potential difference of the combination? Find out the charges on the two capacitors?

Show that in a closed circuit the potential difference between the two ends of a cell is less than the emf of that cell.

Under what condition will the terminal potential difference be more than the emf of a cell?

Statement I: A series LCR circuit when connected to an ac source gives the terminal potential difference 50 V across each of resistor R, inductor L and capacitor C. Then the terminal potential difference across LC is zero. Statement II: The terminal alternating voltages across the inductor and capacitor in a series LCR circuit are in opposite phase.

The terminal potential difference of galvanometter is 1 V for its full-scale deflection. A resistance of 950Omega , connected in series with it, converts it to a voltmeter that can read a maximum of 20 V. What is the resistance of the galvanometer?
