First question - in a closed circuit does the voltage change across resistors? for example. If you start with 20 volts what is the voltage across the resistor/
Second question - does current change across resistors? If you have a closed circuit with one resistor (R1) then two resistors in parallel (R2, R3), is the current passing through R3 just I = V/R3 or I= V/Rtotal?
Thank you very much!
