Question

Your friend claims that a certain circuit contains three capacitors but you don't know if they are wired in series, parallel, or some combination. The battery has a voltage of 9V, two of the three capacitors have capacitances of 2μF while one has a capacitance of 1μF, and your friend claims that if were you to find the correct equivalent capacitance and replace the three capacitors with that, you would find the charge on the equivalent capacitor to be 1.8 x10^-5C. Is this possible?

es it is possible through a wiring that combines series and parallel
		Yes it is possible by wiring all the capacitors in parallel
		Yes it is possible by wiring all the capacitors in series
		No it is not possible because the equivalent capacitance would have to equal the capacitance of just one of the 2μF capacitors
