Three capacitors of 4F, 1.6F, and 17.1F areconnected to the terminals of a 6.2 V

Question

Three capacitors of 4F, 1.6F, and 17.1F areconnected to the terminals of a 6.2 V battery. a) How much energy does the battery supply if the capacitorsare connected in series? Answer in units of mJ b) How much energy does the battery supply if the capacitorsare connected parallel? Answer in units of mJ Three capacitors of 4F, 1.6F, and 17.1F areconnected to the terminals of a 6.2 V battery. a) How much energy does the battery supply if the capacitorsare connected in series? Answer in units of mJ b) How much energy does the battery supply if the capacitorsare connected parallel? Answer in units of mJ

Explanation / Answer

C1 = 4F C2 = 1.6F C3 = 17.1F V = 6.2 V We know that When capacitors connected in series Ceq = 1 / C1 + 1 / C2 + 1 /C3 when capacitors connected in parallel Ceq = C1 + C2 + C3   Formula :         Energy stored in a capacitor U = 0.5CeqV2 Substitute values. Substitute values.
