Is the potential at each point on a circuit same? [duplicate]

Is the potential at each point on a circuit same,if so why? I have read that in order for current to flow through any kind of resistance,the potential of charges reaching resistance is higher than ...

Does 0 resistance lead to constant current? [duplicate]

Consider a wire connected with a battery to complete the circuit. Between any two points on wire, the potential difference is 0. But current however is not zero. It does flow through the circuit. Can ...

How can current flow in an ideal wire if all of its points are at the same potential? [duplicate]

If I have an ideal wire and I connect a battery to it, then the potential drop is zero along the wire, right? So, all its points must be at the same potential. Well, that means charges ( which are ...

Electric Potential in a Circuit [duplicate]

In physics class my teacher is indicating that the electric potential in a wire remains constant until a resistor occurs. If the electrons in the wire are moving away from the negative terminal of the ...

Can Current move without potential difference? [duplicate]

Consider the circuit given below, At the lower left corner of the circuit assume potential to be $0\ V$ , Now at the upper left corner current should be $9\ V$ and similarly at the upper right corner, ...

How current can pass through a part of circuit if potential difference between two points is zero? [duplicate]

Since the wire has no resistance there how can current flow in the circuit between points A and B? If current doesn't pass through them then the circuit doesn't have current

Before and after current passes through a resistor is the potential considered to be constant in the conducting wire? What about V due to battery? [duplicate]

(This is not a duplicate. I am asking this because I am confused with the potential difference provided by battery and the effect of R(resistance) in in determining the potential difference). Recently ...

How can current pass through (resistanceless) connecting wires?

This is not a duplicate of: Will current pass without any resistance?. I read it but my question isn't answered there. I'm a physics tutor for high school students and this is my understanding of how ...

If there was zero potential difference between any two points in a circuit would current still flow? [duplicate]

Suppose there is a wire of zero resistance.So,by Ohms law it must have 0 potential difference between any two points across the resistor,now one connects the wire to a battery which has non-zero ...

How can current flow between points with the same potential?

Shouldn't the ammeter between A and B read zero because A and B are maintained at the same potential, and for current to flow, a potential difference is required? On the other hand, the current that ...

Will any charge flow in this circuit?

I had to find the resistance of this circuit between A and B. My teacher said that since the blank wires have zero resistance, the potential difference across the ends of the blank wire is zero(...

Would current flow through a 0 Ohm wire?

In order for current to flow (from say 12V to 0V) it needs to lose all of its energy (voltage). Resistance is what causes it to lose its energy, so if there was no resistance would there be any way ...
