Should voltage or current be on the y axis?
That’s why what you measured always goes on the y-axis. It’s what you found out: it’s what the experiment was actually about. In our example we changed the voltage and found out about the current so current goes on the y-axis.
What is a voltage versus current graph?
A current–voltage characteristic or I–V curve (current–voltage curve) is a relationship, typically represented as a chart or graph, between the electric current through a circuit, device, or material, and the corresponding voltage, or potential difference across it.
Which axis are used in a graph?
A graph consists of two axes called the x (horizontal) and y (vertical) axes.
What is the slope of voltage vs time graph?
The time constant for the circuit, τ, is the time for the voltage (or current, or charge) to decay to 1/e (≈ 0.368) of its initial value. It is a measure of the response time for the circuit. Hence a graph of ln V vs. t will yield a straight line with slope equal to –1/RC = –1/τ, as illustrated in Figure 3.
When you plot voltage vs current in a circuit and obtain a linear line what is the significance of the slope?
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)
What does the plot of diode current vs voltage mean?
Current-Voltage Relationship The most important diode characteristic is its current-voltage (i-v) relationship. This defines what the current running through a component is, given what voltage is measured across it.
How do you know which axis to plot on?
The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).
How do you find the axis on a graph?
The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a . Example 1: Find the axis of symmetry of the parabola shown.
