What is the graph between potential difference and current?
What is the graph between potential difference and current?
The graph between potential difference and current for a conductor is a straight line passing through the origin.
What is the relationship between the potential difference and current?
The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current.
What does the slope of potential difference and electric current graph represent?
The relationship between voltage and current is Ohm’s Law, and the slope of the line from a graph of the two is the value of the resistance in the circuit.
What will be the nature of graph between potential difference and current for a conductor show in a graph?
it will be a straight line and will show the resistance.. as the potential difference is directly proportional to the current.
What will be the nature of graph between potential difference and current for a conductor name the physical quantity that can be obtained from this graph?
The nature of the graph is a straight line. The physical quantity that can be determined is the gradient of the straight-line graph which is related to the resistance (R) of the conductor.
What is the relationship between potential difference?
Equations
| Equation | Symbols | Meaning in words |
|---|---|---|
| I = Δ V R I=\dfrac{\Delta V}{R} I=RΔV | I I I is current, Δ V \Delta V ΔV is electric potential difference, and R is resistance | Current is directly proportional to electric potential difference and inversely proportional to resistance. |
Which one of the following is correct about the current I and potential difference V across the resistor R in Ohm’s law experiment if one increases the number of cells in it?
Now, according to Ohm’s law, the current is directly proportional to the potential difference applied. Hence, the current will also increase by increasing the number of cells. Hence, option (c) is correct.
When current is plotted against potential difference a straight line passing through the origin is obtained which of the following laws is verified by this result?
By Ohm’s law, voltage across the ends of a conductor is directly proportional to the resistance of the conductor.
What physical quantity can be obtained from a graph plotted against potential difference and current for a conductor?
Name the physical quantity that represents the ratio of potential difference and current. The physical quantity is ‘resistance’. Define one ohm.
How is Ohm’s law verified experimentally what will be the nature of graph between potential difference and current for a conductor?
The value of V/I = R (constant) Plot a graph between V and I by taking V along X- axis along. We get a straight line passing through origin. Conclusion : From the graph between V and I, we conclude that I = V, which is Ohm’s law. Hence Ohm’s law is verified experimentally.
Which device helps to maintain a potential difference across a conductor?
A cell or a battery is used to maintain a potential difference across a conductor.
