1. The problem statement, all variables and given/known data This is just something I want to know, so it doesn't really have a problem statement. But I'm doing a lab tomorrow that uses voltage dividers. So it's two resistors R1 and R2 in series with a power supply. The power supplies Vin (the input voltage). A voltmeter is connected across R2 to measure Vout. The lab also asks me to measure the values of R1 and R2, as well as the current going through R2. I want to make sure I know how to measure each of these properly. 2. Relevant equations 3. The attempt at a solution R1 and R2: connect the multimeter with the power supply disconnected, across the resistors and measure? Vin would just be the amount of voltage supplied by the power supply, correct? I guess I just hook up the multimeter across the terminals of the power supply... Current across R2: Can't I just connect an ammeter in series with the circuit anywhere and take the reading? Can you measure current with a multimeter (I've never used one). Thanks!
