- How did you find PF?
- While I was doing my physics homework and I didn't understand a problem about electric current and resistance.
This is a problem I have been strugglying since I don't know if I should work it together or apart
I ask my teacher and I don't know if I listened well but he told me to use the combine resistance and substract it with the restistance of the material.
You build a wire by combining an 8 inches copper wire with a 10 inches nichrome wire. If their combine resistance is 10 kΩ, find the cross section area of both wires. The nichrome wire has twice the area of the copper wire.
