Web10 de dez. de 2024 · High-Z means high, but not infinite impedance and implies very little current flowing. It is always used over open-circuit if there is enough current for a potential to form for the purposes of … In analog circuits a high impedance node is one that does not have any low impedance paths to any other nodes in the frequency range being considered. Since the terms low and high depend on context to some extent, it is possible in principle for some high impedance nodes to be described as low impedance in one context, and high impedance in another; so the node (perhaps a signal source or amplifier input) has relatively low currents for the voltages involved. razer surround sound speakers amazon simpson meme dont want

"WebThus at resonance, the impedance of the parallel circuit is at its maximum value and equal to the resistance of the circuit creating a circuit condition of high resistance and low current. Also at resonance, as the impedance of the circuit is now that of resistance only, the total circuit current, I will be “in-phase” with the supply voltage, V S .
