Help on Capacitor Impedance Calculations |  |
| Resistance (R) is the opposition to flow of dc; reactance (X) is the same opposition, but to ac in a pure inductor or capacitor. Reactance is variable with frequency - in capacitances inversely. Impedance (Z) is a combination of reactance and resistance.
To find the impedance of a resistor and reactor, simply type in the values. But - if given the impedance and either resistance or reactance, and asked to find the third, there is one important condition: the impedance must be higher than both reactance and resistance. Q is the ratio of reactance to resistance in the circuit, and where appropriate, it will be calculated for you and shown in the answers. The multipliers available for the input of known values range from p to T ... that is from pico- through milli- and Kilo- to Tera-. It is not compulsory to use the available multipliers correctly, eg 0.5µF or 500nF are both acceptable. Note that the default muliplier varies for each input. For your convenience, answers are shown in standard engineering multipliers ranging from one pico-unit (10^-12) to one Tera-unit (10^+12). Results outside this range will not be shown! | ||
