  • What is the capacitive load? - All About Circuits
    Generally, a Capacitive-Load can be considered to be a Short-Circuit to Ground for AC-Amplifiers Therefore, a Resistor is needed to limit the maximum Current demanded from the Amplifier by the Capacitor
  • Capacitive Speakers - All About Circuits
    The capacitive value of the speaker is an important characteristic for the amplifier circuit of the speaker “Piezoelectric means capacitive load” Most amplifier IC’s are developed for electrodynamic speakers They can deliver high current variations and are limited to a voltage level of + - 10 Vpp
  • Why capacitive reactance reduces inductive reactance (by intuition . . .
    I understand why capacitive reactance reduces inductive reactance mathematically, having a result of zero at resonant frequency But how to physically explain the flow of electrons in a series LC circuit, where the coil lags the flow of current (electrons) relative to the applied voltage
  • Question about capacitive reactance - Theoretical vs Lab measured . . .
    Hello all, i need help figuring out my calculations I was asked to calculate the capacitive reactance of a circuit with AC current The capacitor has a value of 470nF For 6 different Hz values (1,10,100, ,100k) i calculated the theoretical capacitive reactance 1hz => 338799 ohms , 10hz => 33879,93 ohms and so on

  • Trying to understand capacitive soil moisture sensor output stage
    Some other configurations using capacitive probes do not use 555 timer instead the higher end capacitive soil moisture probes use a microcontroller that can convert Farads to % moisture or I2C Some of the $12 ESR component testers have capacitance accuracy to about 3pF others (0 25-0 5 pF resolution of a high end capacitance meter)

  • Inductive, Capacitive, and Resistive Circuits
    It boils down to: when you go above resonance the inductive reactance increases while the capacitive reactance decreases, and vice-versa when you go below resonance So the further the frequency deviates from resonance, the more the one reactance will dominate, and the more the phase will shift towards that dominate reactance
