What is the resistance of VI graph?
What is the resistance of VI graph?
So we can define resistance (R) as the ratio of voltage across the conductor to the value of current flowing through it. In a V I graph the slope of the curve gives us the resistance of the material. Also, in parallel and series configuration, the minimum resistance is present for the parallel combination of resistors.
How do you find the resistance of a VI graph?
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. The Ohm’s Law equation can be represented in three ways: R = V / I (resistance = voltage divided by current) V = I x R (voltage = current x resistance)
How do you find the resistance of a slope on a VI graph?
The points on the graph must be determined by calculating with the formula V=IR. You know R,pick a V to get I.I=V/R. If you calculate 2 points,use the slope formula. For each resistance it is a straight line.
What does the slope of a VI graph represent?
Slope of V−I graph represents the Resistance.
How do you find the resistance of an IV graph?
The current at each voltage is proportional to the resistance following Ohm’s law: I = V / R. Therefore, the gradient of the line is equal to 1 / R, enabling the resistance to be extracted from the I-V curve.
What is the resistance of the conductor whose VI graph is given below?
Answer: Explanation: If you simply extend the graph separately to x-axis and y-axis,you got the values of current and voltage easily. So,the resistance is 3/5 ohm.
How does the slope of the line relate to resistance?
The slope of the line is the value of the resistance. A resistor is ‘non-Ohmic’ if the graph of voltage versus current is not a straight line. For example, if resistance changes as voltage changes, the graph of voltage versus current might show a curve with a changing slope.
What does the slope of VI curve in the above experiment indicates?
The slope represents Resistance in this case. The graph of voltage versus current shows the relationship of linearity between the two factors.
How does the slope relate to resistance?
What does the slope of IV graph give?
Slope of a I-V graph for a linear resistor represents its resistance.
Is resistance gradient of Vi graph?
R(V,I)=VI by definition, it is not a gradient.
