What Is Impedance? Is It A Type Of Resistance

[Gingerbolt]

hi i am about to learn about electrical fault loop impedance and i do not have a clue what impedance means. can someone please explain

earth fault loop resistance the low the reading no fault a high reading meaning there is a fault am i correct.

Apparently youre about to learn about it so we probs don't need to bother

exactly. if youre an apprentice, then this is very basic stuff that you will be going over shortly anyway. unless youre a 2/3/4th year apprentice, in which case there is no hope for the future...

Do you know what a resistor is?? Well, in an AC circuit, as well as resistance, because you can have inductance too, [which has a similar effect to resistance in a DC circuit] The resistance to the flow of the current is called impedance to distinguish the two [more or less..]

[Just wait till you get to capacitance]

Problem is though, untill you well and trully understand volts, amps, ohms, impedance, capacitance, inductance and the relationship between them all. learning about EFLI is a total and complete waste of time..

You on some sort of course???

sounds like a re-trainer to me that gave up on teaching.

No, that's infertility.

the condition you are thinking about is when you can't even rise to the occasion.

.....and Resistance is what you encounter when you wish to "practise creating children"......

As John says

Inductance = R + XL (or XC) 

where XL = inductive reactance and XC = capacitive reactance.
