WebThe amount of water in the tank is defined as 1 volt and the "narrowness" (resistance to flow) of the hose is defined as 1 ohm. Using Ohms Law, this gives us a flow (current) of 1 amp. Using this analogy, let's now look at the tank with the narrow hose. Because the hose is narrower, its resistance to flow is higher. WebOct 31, 2000 · The resistance in electrical wires consumes power, and the power consumed increases as the current going through the wires increases. You can see how this happens by doing a little rearranging of the two equations. What you need is an equation for power in terms of resistance and current. Let's rearrange the first equation:

WebAug 22, 2024 · They must be added using the Pythagoras’ theorem. Their sum is equal to the apparent power (VA). Figure 25. Power triangle. When calculating for reactive power, we are still able to use the power formulas. We just have to use them with reactance instead of resistance. I 2 X = Vars. E 2 (inductor voltage) /X = Vars. WebYou said, "...6V power supply", but the Voltage in column C of your table is different in each experiment. Your plot shows two variables, resistance vs. power, but since you are computing power as the product of two variables, Voltage and current, you really have three variables in the experiment: Voltage, current, and resistance.
