How Do You Calculate And Measure The Voltage Drops In A Series Circuit?
It would be better if you provided an actual circuit example. If you have just a few resistors in series, you add them up to get the total resistance. Use ohm’s law with that number and the battery voltage to get the current through the resistors, I = E/Rt. The same current flows through all series resistors. Use that current with each value of resistance to get the voltage across each one, E = IR. Calculate the drop across each resistor as a check, the voltage drops should add up to the battery voltage. To measure the voltage, just connect a voltmeter across each resistor. .
