What is meant by the statement potential difference between A and B is 3v?
Answer: If we say the potential difference between two points is 3 volt it does mean that 3 joule of work is done in moving a unit positive charge between those points.
What is meant by saying that the potential difference between two points is 4?
Answer: The potential difference between two points in an electric circuit is defined as the amount of work done in moving a unit charge from one point to the other point.
What is mean by saying that the potential difference between two points is 1 B?
Ans: When 1 Joule of work is done to move a charge of amount 1 Coulomb from one place to another, then it is said that the potential difference between the two points is 1 Volt (V).
What is meant by saying the potential difference?
BY saying that potential difference between two points is V, we mean that V Joule of work is to be done in moving 1 C charge between those two points.
What is the potential difference between the terminals of the battery?
Hence the Potential difference flowing between the terminals of a battery when 250J of work is done to move a charge of 20C is 12.5V.
What is meant by saying that the potential at a point is 2v?
Two conducting rings of radii r and 2r move in apposite direction with velocities 2v and v respectively on a conducting surface S. There is a uniform magnetic field of magnitude B perpendicular to the plane of the rings. Hence the potential difference betwen the highest points of the two rings is V2−V1=e1+e2=8Brv.
What is meant by saying that the electric potential?
Electric potential at a point is 1 volt means 1 joule of work is done in moving 1 unit positive charge from infinity to that point.
What is the relationship between work done potential difference and charge moved?
The potential difference between two points in an electric circuit is equal to the amount of work done in moving a unit charge from one point to another point.
What is the relation between work done and potential?
The potential difference between two points in an electric field is defined as amount of work done in moving a unit charge from one point to other point. Potential difference = Work Done/ Quantity of Charge moved.
What is the relation between potential and charge?
“At any point in an electric field the electric potential is the amount of electric potential energy divided by the amount of charge at that point. It takes the charge quantity out of the equation and leaves us with an idea of how much potential energy specific areas of the electric field may provide.”
How do you calculate the potential difference between work and charge?
Potential difference is the work done per unit charge. ( 1 V = 1 J C-1) Potential difference in a circuit is measured using a voltmeter which is placed in parallel with the component of interest in the circuit.
How do you calculate the amount of work done?
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. m).
How much is the current with zero potential difference?
Even if you measure a voltage of 0 Volt between two spots with a resistance of (almost) 0 Ohm between them, there is still a current of 0.1 A.
Does current flow between same potential?
Current in a circuit flows because the source, such as a battery, creates an electric field that causes the free electrons in the wire to move. If we connect two equipotential points with a wire, the potential difference across the wire is zero, assuming the two points remain at the same potential after connection.
Is potential difference required for current flow in a wire?
Answer. Answer: The difference in voltage measured when moving from point A to point B is equal to the work which would have to be done, per unit charge, against the electric field to move the charge from A to B. So the answer is , yes, a current can exist in a closed circuit on the the zero resistance wires.
Is voltage needed for current to flow?
Voltage is sometimes described as the ‘push’ or ‘force’ of the electricity, it isn’t really a force but this may help you to imagine what is happening. It is possible to have voltage without current, but current cannot flow without voltage. current can flow. current cannot flow.
