Many apologies - this is probably the noobiest question ever asked.

I have been trying to measure really simple circuitry (battery, breadboard, wires and resistor) with a multimeter.

I cannot get the figures I am measuring to add up to the expected values.

So I looked at the following page for help https://www.autodesk.com/products/e...standing-voltage-current-resistance-ohms-law/

If you look at the bottom of the page then the writer plugs the numbers into Ohm's Law and says "R = 9V/0.016A which equals 473.68"

Now unless I have missed something totally, 9 divided by 0.016 equals 562.5, not 473.68

Please can someone tell me what I am doing wrong here ?

Thanks

Ben
