ohms law cartoon When it comes to electronics, I don’t normally use a lot of algebra, but the Ohms rule is incredibly useful! Georg Ohm discovered the rule, which is based on how voltage, current, and resistance are associated.
Examine the diagram above to see if it makes sense to you that: When you raise the voltage in a circuit while keeping the resistance steady, you get more current.
When the resistance in a circuit is increased while the voltage remains constant, the current decreases. Ohm’s law is a mathematical formula for defining the relationship between voltage, resistance, and current.
ohms law cartoon explained
Ohm’s theorem is aptly summed up in this cartoon. Volt is attempting to drive Amp through the conductor, but Ohm is doing all he can to limit Amp. With a little creativity, you can see that the further (stronger) Volt drives, the more Amp gets through. Ohm, on the other hand, can get through fewer if he pulls on the rope (resists).
All three are in absolute harmony and proportion to one another. Ohm’s law is the maxim that holds them in place.
What is a volt
A volt is a unit of electric potential, also known as electromotive force, that represents “the potential difference between two points of a conducting wire carrying a constant current of one ampere when the power dissipated between these points is one watt.”
In other words, when a current of one ampere passes across a resistance of one ohm, a potential of one volt occurs through the resistance.
What is an amp
An amp, short for ampere, is a unit of the electrical current defined by SI by calculating the electromagnetic force between electrical conductors carrying electric current. The ampere is the constant current that, if retained in two straight parallel conductors of infinite duration and negligible circular cross-section and put one meter apart in vacuum, would create a force equal to 2×10−7 newtons per meter of length between these conductors.
What is an ohm
The ohm is characterized as an electrical resistance between two points on a conductor when a constant potential difference of one volt is applied to these points and induces a current of one ampere in the conductor, the conductor not being the seat of any electromotive power.
