If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …

This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V. Can you use 20V, 25V or even higher? The answer is yes. It
Replacing Capacitors in Old Radios and TVs
Note that two of these types—mica capacitors and flat molded paper capacitors—look similar. Both are flat, often with color coding dots to indicate the value. It is easy to tell them apart by checking the value. Mica capacitors have very small values, typically under .001 mfd., typically under .001 mfd.
