Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An electric current will always follow
A
the path of least resistance
B
a path toward the north pole
C
a path toward the south pole
D
the path that leads through insulators
Explanation: 

Detailed explanation-1: -No, electricity does not “take the path of least resistance.” It takes all paths available-in inverse proportion to the impedance of the paths. Current flows through all available paths. The magnitude of the current flowing in each path depends on the voltage and impedance of each path.

Detailed explanation-2: -"Current takes the path of least resistance” is just a phrase people say but it’s not totally accurate. When one path through the circuit has 0 resistance (a short), it is true that current follows that path only. It isn’t true when you have multiple paths, with nonzero resistance, though.

Detailed explanation-3: -The path of least resistance is the physical or metaphorical pathway that provides the least resistance to forward motion by a given object or entity, among a set of alternative paths. The concept is often used to describe why an object or entity takes a given path.

Detailed explanation-4: -Energy moves down the path of least resistance, be it water in a river or electricity through a circuit. Your life is the same way-it moves down the path of least resistance.

Detailed explanation-5: -Therefore, electric current always flows from higher to lower potential.
