# Why does any charge flow through a parallel branch with a higher resistance? [duplicate]

Consider a circuit with a 1 $\Omega$ resistor and a 2 $\Omega$ resistor in parallel. If it takes twice as much energy to send an electron through a 2 $\Omega$ resistor than a 1 $\Omega$ resistor, why do any electrons flow through the 2 $\Omega$ resistor? Wouldn't it be more efficient to send all the electrons through the 1 $\Omega$ resistor?

Current flows through both branches of the parallel circuit, so this logic is obviously flawed, but I don't understand why.

• Maybe they need teamwork to get through the resistance :D

• Current flows because there's a potential applied, and Ohm's law describes current as a result. The 'more efficient' concept is not applicable. Commented Jan 6, 2017 at 13:10
• The question is essentially equivalent to "Why does water flows through a small hole in a barrel if there is a bigger one in it" Commented Jan 6, 2017 at 13:22
• The battery does not have a mind. It does not decide which route is more efficient. Commented Jan 6, 2017 at 14:19
