Question

We are working on Ohm's law right now and I have a problem that I just can't solve. It's that there are two 10 ohm resistors in a series, which is parallel to a 100 ohm resistor and the battery. I can get all of the resistances, the batteries current, and I know that the 100 ohm resistor would be 9 volts as that's what I was given for the battery. I'm trying to get the current for all the resistors, but it doesn't add up whenever I try it. I also need to find the voltage for the two 10 ohm resistors.

Answer

$$I _ {X 3} = \frac {V _ {c}}{R _ {X 3}} = \frac {9}{100} = 0,09 (A)$$ $$V _ {X 3} = 9V$$ $$I _ {X 1} = I _ {X 2} = \frac {V _ {c}}{R _ {X 1}} = \frac {V _ {c}}{R _ {X 2}} = \frac {9}{20} = 0,45 (A)$$ $$V _ {X 1} = V _ {X 2} = I _ {X 1} * R _ {X 1} = I _ {X 2} * R _ {X 2} = 10 * 0,45 = 4,5 (V)$$
