What are the equipments used in ohm law?
Your question in ambiguous. Are you asking what equipment you need to provewhether or not Ohm's Law applies to a particular load? If so, then you need a variable voltage supply, a voltmeter, and an ammeter. As you gradually increase the voltage across the load, you will need to record the voltage and current values. If the resulting graph is a straight line, then the load is 'ohmic' (or 'linear') and obeys Ohm's Law. If the resulting graph is a curved line, then the load is 'non-ohmic' (or 'non-linear') and does not obey Ohm's Law.
What is the ratio of rms load voltage to mean load voltage?
The mean load voltage, in other words the average voltage, is zero in an ac system.
What do you understand by regulation in a transformer?
Regulation of transformer means percentage reduction of transformer secondary voltage due to transformer loading as compared to its no load voltage.Another AnswerA transformer's voltage regulation is defined as 'the change in its secondary voltage, from no-load to full-load, at a specified power factor, expressed as a percentage of its full-load voltage, with the primary supply voltage held constant'.
Why does the terminal voltage decreases as the load current increases?
A: That will happen anytime the voltage source is not able to provide the power needed for the load. If the load exceed the power available from the source the voltage will be reduced as IR drop from the source
When a load is connected to the output voltage divider the output voltage will what?
When a load is connected to the output of a voltage divider, the output voltage will typically decrease due to the loading effect. This occurs because the load draws current, which can change the voltage across the resistors in the divider. The extent of the voltage drop depends on the resistance of the load relative to the resistors in the voltage divider. If the load resistance is significantly lower than the divider resistances, the output voltage will drop more noticeably.
Is there any similarity between the graphs plotted between voltage and current?
When you plot a graph of voltage against current, you can end up with a straight line or a curved line.If you have a straight line, then it shows that the change in current is directly proportional to the change in voltage and, so, the circuit is obeying Ohm's Law. If the graph is a curve, then the change in current is not proportional to the change in voltage and, so, the circuit is not obeying Ohm's Law.In the case of a straight-line graph, the gradient of the graph indicates the resistance of the circuit. The greater the gradient, the higher the circuit resistance.In the case of a curved-line graph, the gradient (i.e. the tangent) at each point along that curve will indicate the (changing) resistance at each of those points.
What is the gradient of a graph in a displacement time and velocity time graphs?
In a displacement-time graph, the gradient represents velocity. In a velocity-time graph, the gradient represents acceleration.
Can the spring constant be found by the gradient of the graph?
The answer depends on what the graph is of!
What is valtage gradient?
Probably an incorrect spelling of voltage gradient.
What does the gradient of a line on a distance-time graph tell us about an object?
The gradient of a distance-time graph gives the object's speed.
What equal accleration on a speed vs time graph?
The gradient of the graph.
Can the scale of a graph affect the gradient calculation?
Not if the gradient calculation is done correctly.
How do you plot ohms law graph of potential difference versus current?
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.
How do you calculate line regulations?
no load voltage - full load voltage by full load voltage

What is the gradient of acceleration time graph?
The gradient of an acceleration-time graph represents the rate at which the acceleration is changing over time. If the gradient is positive, it indicates an increase in acceleration, while a negative gradient indicates a decrease in acceleration. A horizontal line on the graph would represent a constant acceleration, where the gradient is zero.
What feature of a distance per time graph represents speed?
The gradient (slope) of the tangent to the graph at the given time - provided that it exists. If the graph is a straight line at that point, it is the gradient of that line.
