Find the current through the resistor R1.
The Attempt at a Solution
First I short circuited the voltage source and determined I1.
I1=(9A)(10-olms/18-olms)=5 A down
Next, I short circuited the current source and determined the current going through R1 via olms law.
I2=18V/18-olm= 1 A up
Therefore, the total current flowing through the resistor R2 is 4 A down
Does this seem right?
