OHM’S LAW E I R
OHM’S LAW E E=the electromotive force I= the electron flow or current in amperes R= the resistance in ohms I R
What is the total circuit resistance Rt? Rt=4 ח + 2 = ח 6 ח What is the current? I=E/R 2 A =12 V/6 ח What is the voltage drop across the resistors? 2 ח resistor E=I x R 4 V =2 A x 2 ח
What is the voltage drop across the 4 ohm resistor? E=I x R 8 V=2 A x 4 ח
