(b) Q = C eq V. Substituting the values, we get. Q = 2 μF × 18 V = 36 μ C. V 1 = Q/C 1 = 36 μ C/ 6 μ F = 6 V. V 2 = Q/C 2 = 36 μ C/ 3 μ F = 12 V (c) When capacitors are connected in series, the magnitude of charge Q on each capacitor is the same.The charge on each capacitor will equal the charge supplied by the battery. Thus, each capacitor will have a charge of 36 μC.

There are two simple and common types of connections, called series and parallel, for which we can easily calculate the total capacitance.

Notice that in some nodes (like between R 1 and R 2) the current is the same going in as at is coming out.At other nodes (specifically the three-way junction between R 2, R 3, and R 4) the main (blue) current splits into two different ones. That''s the key difference between series and parallel!. Series Circuits Defined. Two components are in series if they share a common node …

Resistors in Series. Resistors are in series whenever the flow of charge, or the current, must flow through components sequentially. Resistors in Series: These four resistors are connected in series because if a current was applied at one end, it would flow through each resistor sequentially to the end.. shows resistors in series connected to a voltage source.
$begingroup$ Yes because in parallel voltage is the same. In series, current is the same. For series, zero current = charging has stopped. For parallel, same voltage = they are charging together so when one stops so does the other. Note that fully charged does not necessarily mean same voltage (i.e. it does in parallel but not in series).
For capacitors connected in parallel, the total capacitance (also known as the equivalent capacitance) is just the sum of the individual capacitances: . #C_(eq) = C_1 + C_2 + C_3 ...# For capacitors connected in parallel, it is like having a capacitor with a larger plate area, which allows it to hold more charge when connected to a certain voltage, which means that the total …

Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates.
