Help on Tuned Circuit Calculations |  |
| A tuned circuit is a series or parallel combination of inductance, capacitance, and (usually) resistance. At a particular frequency, the reactance of the inductance and capacitance become equal, and the impedance of the circuit becomes very low (series combination) or high (parallel).
In tuned circuits intended for use in radio equipment, the same formula may be used for both series and parallel tuning without serious error (less than 1% if Q is 10 or higher). 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 - if not less than unity. 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 0.5µH or 500nH 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! | ||
