Hi Guys
I’m using a SUT and I need to put resistors on the primary side. I’ve used an online calculator and it comes out at 21ohms. So two things really
1) Do I go for 20 or 22ohms - I would be trying to use a 1% tolerance to minimise the differences between channels
2) What type of resistor, carbon, metal film etc should I be using. I would like to say that money is no object but of course that’s not true so a compromise will be required.
Many thanks
