WebMar 26, 2016 · The most important thing to remember about Ohm's law is that you must always do the calculations in terms of volts, amperes, and ohms. For example, if you measure the current in milliamps (which you usually will in electronic circuits), you must convert the milliamps to amperes by dividing by 1,000. For example, 250 mA is 0.25 A. WebOhms law describes how Voltage, Current and Resistance relate algebraically, stating Voltage (E) = Current (I) multiplied by Resistance (R) E=IR or you can rewrite it many ways I=E/R R=E/I So lets do an example, We have a circuit consisting of a 12v Battery and a resistor measuring 2 Ohms. bmw that looks like a box

Explain the ohm's law

WebOhm's Law Combining the elements of voltage, current, and resistance, Ohm developed the formula: Where V = Voltage in volts I = Current in amps R = Resistance in ohms This is called Ohm's law. Let's say, for example, that we have a circuit with the potential of 1 volt, a current of 1 amp, and resistance of 1 ohm. Using Ohm's Law we can say: In circuit analysis, three equivalent expressions of Ohm's law are used interchangeably: Each equation is quoted by some sources as the defining relationship of Ohm's law, or all three are quoted, or derived from a proportional form, or even just the two that do not correspond to Ohm's original statement may sometimes be giv…
