If the cross sectional area of a cable is increased, what will happen to the voltage drop?
- Decrease.
- Increase.
- Stay the same.
Azfar asking:
why does the voltage drop decreases? According to my understanding, V=IR. When cross sectional area increases, resistance will increase, hence increasing the voltage. Are voltage and voltage drop both different things?
