“Ohm's Law is the relationship among electric current, resistance, and voltage. The principle is named after the German scientist George Simon Ohm.” –Webster’s Online Dictionary. I will be discussing the uses of Ohm’s Law and why it is so important in everyday electrical problems whether it be simple or not. It is everywhere and used by many whether they notice it or not.
Ohms law states that current in amperes is equal to voltage divided by resistance. This form of ohms law is most useful for technicians because it is easy to measure voltage with a voltmeter. Connect negative lead of your voltmeter to ground or power source return line and you can measure the voltage on as many things that are accessible to your meter probe that you want. We used this many times when we were calculating current, voltage, or resistance in our labs. It served to be quite a useful shortcut so you don’t have to keep using the equipment......
