WebThe flow of electrical current splits in the same way. It is not random, because it is based on known principles. For resistors in parallel, that principle is Ohm's Law. If you know Ohm's Law, and you realize the voltage on the two resistors is the same, you can solve for both currents. 1 comment. WebA parallel circuit decreases the resistance compared to a circuit where there are no parallel branches. Say you had 2 100 ohm resistors in parallel. Then you add a third 100 ohm resistor in parallel with the first two. Now the current has three path to go through compared to two, so it increases.
