... b. Turn on and test the power supply. Note that whenever power is on, either a green or a red indicator light will light up: green indicates normal (constant voltage) operation and red indicates the current limit has been reached. • Use the coarse and fine adjust knobs to vary the output voltage. Wh ...

Ohm`s law. Linear Regression.
... Ohm’s law states that at a constant temperature these two physical quantities are directly proportional. That is, for a 10% increase in voltage there is also a 10% increase in current intensity. This is equivalent to saying that the ratio between the two is constant. This constant is named electric ...

Josephson voltage standard
A Josephson voltage standard is a complex system that uses a superconductive integrated circuit chip operating at 4 K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact. It is the most accurate method to generate or measure voltage and, by international agreement, is the basis for voltage standards around the World.
