how could i lower the impedance affecting a certain material. I am sure there is a circuit i can use to do this can anybody help??

Daniel Floyd said:ok I am sorry guys i may not have made this verry clear. for instance crystals have a high impedance which causes low current can i either step this current up or do something to lower the impedance.
Daniel Floyd said:im not saying i want to lower the impedance of crystal i was just using it as an example mate. i bassiclly have like high voltage and low current of a circuit and i need to some how gain more current. one way was lowering the impedance of like copper (for example) which should higher the current or i was thinking like a transformer.
truesearch said:Good luck Daniel, glad to have been of help.
Daniel Floyd said:ok guys there is no application other then a simulation I am just playing around learning things, I bassiclly have multi-sim with an AC power source which is being converted into DC power using the full wave rectifier circuit but i want to be able to put a low AC current into the circuit and have a high DC current out of the circuit to get such a low current i have added a high impedance value but i was wondering if i could create a circuit to counteract this impedance or weather i could like use a transformer to step up current rather then voltage?
... has this made it any more clear.

Impedance is a measure of the opposition to the flow of electrical current in a circuit. It is represented by the symbol Z and is measured in ohms.
Lower impedance allows for more efficient transfer of electrical energy in a circuit. This means that less energy is lost and the circuit can operate more reliably and with less heat dissipation.
There are several ways to lower impedance in a circuit. These include using thicker wire or traces, reducing the length of the circuit, and using components with lower impedance values.
Some common circuit solutions for lowering impedance include using bypass or decoupling capacitors, adding inductors to filter out high frequency noise, and implementing ground planes to reduce ground loop impedance.
While lowering impedance can have many benefits, it can also increase the cost and complexity of a circuit. Additionally, if not done carefully, it can lead to unwanted resonances and signal distortions. It is important to balance the benefits and drawbacks when designing a circuit with lower impedance.
