Essential AC Circuit Terminology and Definitions

Definitions AC. The changing of direction.
CURRENT. The meaning does not change, but may change in value. CURRENT PERIODIC. That which is repeated in cycles with the same period. PERIOD. Time it takes one cycle. CYCLE. Set starting values such that at any one walking back to the all the values of the signal. FREQUENCY. Number of cycles a second. The unit hertz. Resonance frequency is that frequency that makes a circuit is resistive (the circuit contains inductors and capacitors). Or half-power frequency cut-off frequency filter. That often happens in these situations simultaneously: the power half the maximum, the load voltage is 70% of the maximum, the phase angle is 45 degrees. BANDWIDTH. Difference between the cutoff frequencies. OR QUALITY FACTOR amplification factor of a series circuit. The relationship between the voltage of the coil or capacitor and the total stress. ANGULO or time lag of one CIRCUTTO. is the difference expressed in angle or in time between stress and total intensity. BALLAST inductive and capacitive. Opposing the inductor and capacitor respectively to the passage of alternating current. Its unit is the Ohm. IMPEDANCE. General opposition to any body to the passage of alternating current. Its unit is the Ohm. SUBCEPTANCIA, inductive or capacitive. Ease of inductor and capacitor respectively to alter current flow. Its unit is the siemens. Admittance. Facility in general of any body to the passage of alternating current. Its unit is the siemens. Instantaneous values. The value at any given time. Peak value, CRESTA, or Maximum. Maximum instantaneous value. VALUE peak to peak. Distance from the peak value from positive to negative. AVERAGE VALUE OR VALUE OF CURRENT VALUE OF A SIGNAL OFFSET. It is the arithmetic mean of all the instantaneous values. RMS or HEAT. Value a current that causes the same thermal effects. ACTIVE POWER.'s really turned into another form of energy. His unit watt. REACTIVE POWER. The apparently consumed in capacitors and inductors. The unit the volt-ampere reactive. APPARENT POWER. The seemingly consumed by a circuit. His unit the volt-ampere.
