This is probably plainly easy! But if someone could explain what im missing i would be greatful !
I found a step down transformer 230/24 So thats 9.6:1 ratio.
I wanted to measure the average current to a load via this. I'd use it as a current transformer.
I put a 1Ohm resistor across the primary. And put the secondary winding in series with the load. I measured across the resistor.
But now i'm unsure of what to do.
I have the transformer ratio of 9.6:1 and the 1ohm resistor
From the scope i can see the current waveform, i can see the Peak voltage. This is what i want to use i think?
Iv used loads that i "know the current through" adn have checked with a meter but i just don't know how to arrive at it via the scope info, transformer ratio and resistor value.
Also when i get another probe so i can use to channels
If i overlay the voltage waveform on top of the current waveform will this represent which is leading or lagging? If so how can i find by what angle?
Cheers
