Ohm’s Law & Watt’s Law


Ohms law states that Current is directly related to Voltage, and inversely related to Resistance

The relationship between two variables is a direct relationship if when one increases so does the other or as one decreases so does the other.

If current is directly related to voltage, and voltage increases Current will also increase. If one goes up the other goes up. If one goes down the other goes down.

An inverse relationship, also known as indirect relationship, is a relationship between two variables in which they move in opposite directions

If Current is inversely related to Resistance, and resistance increases Current will decrease. If one goes up the other goes down.
