Can current flow when potential difference is zero?

Since there is no potential difference,the current flowing through the circuit will be zero. If the resistance becomes zero(i.e short circuit) the current will still not flow as there is no potential difference.

What will happen to the current if the resistance is zero?

When the resistance in any circuit is equal to zero then the current passing through that circuit will be infinite.

Why does no current flow if there is no voltage?

The current is dependent on voltage. The voltage is the difference between points. It is the force that allows electrons to move from one point to another. If the voltage is absent, those electrons cannot move between points in a circuit, which means that the current does not exist.

What does it mean if potential difference is 0?

0 potential difference between two locations means that the potential values AT each point are the same.

What does it mean to have zero resistance?

Zero resistance means an infinite time constant – the current does not decay, but persists indefinitely (or as long as the material remains superconducting).

What is the potential difference across a region with zero resistance?

Now suppose the wire has zero resistance. That means any electrons flowing through it don’t slow down, so no extra energy needs to be added to the electrons, so the voltage difference between the ends of the wire can be zero.

Why potential difference in a wire is zero?

So knowing the voltage helps us calculate how much potential energy would be lost or gained when charges move from one point to another. Well, that’s because we assume there is no loss in potential energy as charges move through this wire. And therefore, the potential difference between these two points is zero.

What is the potential difference when the resistance is 0?

When the resistance is 0 there’s no need of a “potential difference”. The current doesn’t need that “push (potential difference/voltage)” when there’s no opposition (resistance) in the circuit. E.g: we need to throw/push (voltage) the ball (current) upwards to make it go up because there’s gravity (resistance) which is pulling it down.

When will electric current flow in path with zero resistance?

As electric current will flow in path with zero resistance when a zero resistance path and finite resistance path are in parallel combinations. In a Wheatstone bridge, the resistors have a finite Stack Exchange Network

Can electric current flow through a wire with a 0 potential?

No electric current can flow in this condition in both series and parallel connections. As an example when one end of the wire is +6 volts and its other end is also +6 volts the difference in potential is zero volt. The current through this wire is zero.

What does it mean when voltage is zero on a wire?

Electric current is usually compared to water current. When the voltage is zero, it means that the left end of the wire has the same potential with In a level pipe water will not flow from one end to the other end. There must be a difference in potential for the water to flow through the long pipe.
