Electrical Electronic Engineering Ohm S Law Current Voltage Our ohm's law calculator is a neat little tool to help you find the relationships between voltage, current and resistance across a given conductor. the ohm's law formula and voltage formula are mainly used in electrical engineering and electronics. also, if you know how to calculate power dissipation, you may find it very useful when studying. To help us understand the relationships between the various values used to calculate ohms law a little further. we can take all of the previous ohm’s law equations for finding voltage, current, resistance and of course power, and condense them into a simple ohms law pie chart for use in ac and dc circuits and calculations as shown.
Formula For Current Voltage Power Resistance Coolguides The 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. This gives the power in terms of only the current and the resistance. thus, by combining ohm’s law with the equation p = i v p = i v for electric power, we obtain two more expressions for power: one in terms of voltage and resistance and one in terms of current and resistance. note that only resistance (not capacitance or anything else. Ohm's law states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. introducing the constant of proportionality, the resistance, [1] one arrives at the three mathematical equations used to describe this relationship: [2] where i is the current through the conductor, v.
