- Inductive, Capacitive, and Resistive CircuitsIt 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.
- Capacitive Voltage divider - All About CircuitsMy AC source is 230 V 50 Cycle. I have quite a few voltage adapters that function ONLY on 110 Volt. Rather than use a Transformer 230 V to 110 Volt I thought of using Capacitive voltage divider. Using TWO 0.47 Uf X2 capacitors and 1K ohm resistor,( all in series) I manged to get 110 Volt AC on...
- Morse Keyer Project - All About CircuitsAtmel has a range of capacitive touch sensor IC's with identical or similar properties to the ones used in that kit. The cheapest ones that are suitable are less than $1 each, but those are SMD devices. If you don't mind using SMD, the AT42QT1010 at about $.75 is a good choice.
- Resistive vs Capacitive vs Other? - All About CircuitsThe capacitive humidity sensors I played with a long time ago used a thin plastic sheet that changes thickness with changes in humidity. The surfaces of the plastic were metalized to make a very small value capacitor. When the thickness changes, the capacitance changes (basic physics).
