Your question is Measuring Power Supply Input and Ripple. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you measure the input current of a power supply that has a supply voltage of 120V and outputs 5V at 5A with a 1 ohm load resistor, and how would you measure the ripple effect of the output voltage?
