Electrical Power Vs Current Graph

The power through the resistor is given by.

Electrical power vs current graph. Volatge vs current graphs for typical components. The figures along the bottom horizontal axis represent current in amperes. Power is measured in watts w kilo watts kw mega watts mw and giga watts gw. Another thing you could do is use the oscilloscope and use input a as the voltage and input b as the current.

Devices which have i v curves which are limited to the first and third quadrants of the i v plane passing through the origin are passive components loads that consume electric power from the circuit. You ll need to be aware of how the current voltage. The following illustration shows how a time current curve works. So the energy work done is given by the root mean square rms current is defined as.

But we must take the average of this power over time t to calculate the energy work. Voltage is the electrical force that would drive an electric current between two points. A lightbulb uses 100 watts of power. A graph of power shows swings up and down sometimes to zero as things turn on.

A compressor uses 14 kw when it is running. Contents 1 relationship between voltage and current 2 circuit 3 symb. Current is the rate at which electric charge flows past a point in a circuit. The power of a load can change quickly especially if the load is turning on and off.

Here not only does the current value vary but its direction varies too. Add a current probe for the load current and add it to the graph you can use drag and drop then set the cursor over the graph and click space. In computational biology power graph analysis is a method for the analysis and representation of complex networks power graph analysis is the computation analysis and visual representation of a power graph from a graph. It extends graph syntax with representations of cliques bicliques and stars.

Conventional current always flows through these devices in the direction of the electric field from the positive voltage. I rms is the square root of the average of the current. Power graph analysis can be thought of as a lossless compression algorithm for graphs. Time current curves are used to show how fast a breaker will trip at any magnitude of current.

Graph of power related to changing current referring to figure 16 on page 33 note that power also varies as the square of current just as it does with voltage. These are some simple relationships for v vs i graphs. Examples are resistors and electric motors. V t is our voltage as a function of time which means that our voltage changes as time changes.
