Asked by Cherie
In a series circuit, the power source is 9-volt battery and three resistors.
R1=7ohm
R2=9ohm
R3=2ohm
What is the total resistance in this series circuit?
What is the current?
Please help I don't understand this!, Thank you

If the resistors are all in SERIES then the total resistance is the sum:
7 + 9 + 2 = 18 ohms
i = V/R = 9/18 = 0.5 amperes
7 + 9 + 2 = 18 ohms
i = V/R = 9/18 = 0.5 amperes
