Learn Ohm S Law

Ohm s law is a formula used to calculate the relationship between voltage current and resistance in an electrical circuit.

Learn ohm s law. In short if you know two of these three quantities you can calculate the third. Ohm s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Ohms law for dummies. Resistors in this experiment we will use digilent s analog discovery and a digital multimeter to explore a fundamental equation used in electric circuit analysis and design.

Where i is the current through the conductor in units of amperes v is the voltage measured across the conductor in. Ohm s law describes the relationship between the voltage across a resistor and the resulting current passing through the resistor. Go back if you dare to your high school algebra class and remember that you can rearrange the terms in a simple formula such as ohm s law to create other equivalent formulas. Introducing the constant of proportionality the resistance one arrives at the usual mathematical equation that describes this relationship.

Electricity is an extremely difficult concept to understand which is why today you re going to learn from me a dummy how i learned the fundamentals of electricity. To students of electronics ohm s law e ir is as fundamentally important as einstein s relativity equation e mc is to physicists. Analog discovery ohm s law project 1.
