![]() Likewise, the slower the voltage changes the less current will flow. Since capacitors charge and discharge in proportion to the rate of voltage change across them, the faster the voltage changes the more current will flow. Like resistance, reactance is measured in Ohm's but is given the symbol X to distinguish it from a purely resistive R value and as the component in question is a capacitor, the reactance of a capacitor is called Capacitive Reactance, ( X C ) which is measured in Ohms. ![]() If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors. ![]() ![]() When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors' capacitances. Use a calculator for more accurate numbers. Note: math is simplified for illustration purposes. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacing of the individual capacitors.ġ / 12 = 0.083, 1 / 20 = 0.050, 1 / 30 = 0.033 When capacitors are connected in series, the total capacitance is less than any one of the series capacitors' individual capacitances. What is the total capacitive reactance (X C) when connected in series or connected in parallel? Step 1: Find the total capacitance of the circuitĪssume we have three capacitors, a 12 ♟, a 20 ♟, and a 30 ♟ connected to a 60Hz source.
