Ohm's Law can be rewritten in three ways for calculating current, resistance, and voltage. If a current I should flow through a resistor R, the voltage V can be calculated. First Version of the (voltage) formula: V = I Ã R. If there is a voltage V across a resistor R, a current I flows through it.
The most important thing to remember about Ohmâs 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. Here are a few other things you should keep in mind concerning Ohmâs law:
