I'm confused about the value of this machine
https://irishelectronics.ie/epages/950018241.sf/en_IE/?ObjectPath=/Shops/950018241/Products/LABPS1503
This machine allows us to alter V and I
According to Ohms law, if we apply 10v To a circuit with 1kohm resistor the I is 1mA
But if we used that machine to increase I from 1mA to anything larger how does that react with Ohms law?
If we can set V (with first dial on Machine) I (2nd dial) and R (using resistors) how does the law remain true when each value can be altered?
