P. 4690. Two well-insulated condensers are charged on order to experiment with them. If they are connected in series, such that the oppositely charged terminals are connected, then altogether 166 V is measured across them. If they are connected in parallel, such that the same terminals are connected then the voltage across them is 74.4 V. In this latter case the energy loss is equal to the original energy of that condenser of capacitance \(\displaystyle 10~\mu \rm F\), which had smaller voltage across its plates.
\(\displaystyle a)\) What was the original voltage of the two condensers?
\(\displaystyle b)\) What is the capacitance of the other condenser?
