Three 1.5 V cells are arranged in series, powering a circuit that has two operations with equivalent resistances of 229 Ω (connecting to the positive terminal) and 393 Ω that meet in a single, metered connection. There is a 17 μC capacitor that bridges between the connection and the negative terminal. (a) If the potential on the negative side of the battery is -0.5 V, then what is the potential on the positive side of the battery? V ( b)...

Remember that the current coming into a junction equals the current coming out of the junction. Also bear in mind that voltage is basically a height difference between two points. 1) If you measure the potential across two batteries and find that V1 = 1.3V and V2 = 1.4V, then you measure the potential between the negative ends of battery 1 and positive end of battery 2 and get V12-+ = -0.1 and the potential between the positive ends of...
