The current is represented by the horizontal (x) axis, and the potential difference is represented by the vertical (y) axis.

If the resulting graph is a straight line, then it confirms that the circuit is obeying Ohm's Law. If the resulting graph is a curve, then the circuit does not obey Ohm's Law.

The gradient at any point along of the resulting line represents the resistance of the load for that ratio of voltage to current.

What is the shape of graph of voltage versus current for an ohmic material?

Linear.


How do you set out a line graph showing current vs voltage?

its like a bar graph but with little crosses and you join them up with lines


Why is the resistance vs current graph is not linear?

resitance is inversly proportional to current when (v) is kept constant <><><><><> Because resistance is a function of temperature.


What is the zener region?

The zener region describes the area on the performance curve (a graph of voltage across versus current through the junction) of a zener diode. The diode acts like a "regular" diode in the forward biased direction. When some 0.7 volts or so is reached, forward current begins to climb rapidly as voltage is increased (for silicon diodes.) But in the reverse direction recall that as the diode is reverse biased, a small amount of current will flow (because of minority carriers). This "trickle" of current will continue until the "zener voltage" is reached, and then the diode will begin to conduct heavily. On the graph, this is the zener region. Zener diodes can be made to breakdown at a specific voltage, and their ability to conduct reverse current can be increased by manufacturing a larger diode. That means there are a range of voltages and wattages of zener diodes available. Wikipedia has more information and that graph. Use the link provided to get there.


What does the slope of voltage-current curve represent?

It depends. If voltage is drawn along the horizontal axis, then the slope at any point on the graph represents the reciprocal of resistance at that point. If current is drawn along the horizontal axis, then the slope at any point on the graph represents the resistance at that point.

What is the difference frequency graph versus percentage graph?

The main difference is that the vertical scale for a frequency graph is in units (or numbers) whereas in a percentage graph, it is in percentages,


What does the slope of a graph potential difference vs current represent?

The slope of a graph of potential difference vs current represents the resistance of the component or circuit being analyzed. It is calculated using Ohm's Law: V = IR, where V is the potential difference, I is the current, and R is the resistance. A steeper slope indicates a higher resistance, while a shallower slope indicates a lower resistance.

How do you calculate potential difference from a graph?

To calculate the potential difference from a graph, you need to determine the vertical distance between two points on the graph that correspond to different potential values. This vertical distance represents the potential difference between those two points. You can measure this distance using the scales on the axes of the graph.


Why is the gradient on a current-potential difference graph not the resistance?

Resistance is defined by R = V/I where V is potential difference and I is current. It is not: change in pd / change in current - which would be the gradient of the curve. Thus to measure the resistance at a particular pd we simply read off the current at that pd and use the equation above. The problem stems from the way resistors are introduced before non-ohmic components, and for ohmic components it may appear that the gradient is being used for the resistance.


What relationship is depicted in the potential energy versus internuclear distance graph?

The potential energy versus internuclear distance graph shows the relationship between the energy of two atoms or molecules as they move closer or farther apart. It illustrates how the potential energy changes as the distance between the nuclei of the atoms or molecules changes.


How does a graph showing speed differ from a graph showing acceleration?

Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.


Does the slope of a speed-versus-time graph represents acceleration?

No, the slope of a speed-versus-time graph represents the rate of change of speed, not acceleration. Acceleration is represented by the slope of a velocity-versus-time graph.


What shape would the graph of U versus x have if a particle were in a region of neutral equilibrium?

In neutral equilibrium, displacement in either direction would not affect the potential energy of the particle, therefore, the graph would be horizontal.


What shape do you expect for a graph showing the position of a motorcycle versus time if the motorcycle is speeding up with a constant acceleration?

What does the voltage and current graph show in a circuit?

The voltage and current graph in a circuit shows the relationship between voltage (electrical potential) and current (flow of electricity) over time. It helps to understand how these two factors interact and affect each other in the circuit.


How is the peak potential difference shown?

The peak potential difference is the maximum voltage that can be measured in an electrical system. It is typically shown on a graph as the highest point along the voltage axis. In an oscilloscope display, the peak potential difference is indicated by the highest point reached by the waveform.
