DrDanger said:Currnet flows from positive to negative right? cause you assume the path a proton would take?!
also how much resistance does one ohm provide?
does it block 1 volt? and resistors increase voltage and decrease current right? thanks!
Ohm's Law is a fundamental principle in physics that describes the relationship between resistance, voltage, and current in an electrical circuit. It states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them.
Resistance is the measure of how difficult it is for current to flow through a material. It is measured in ohms (Ω) and is affected by factors such as the type of material, its length, and its cross-sectional area.
Voltage, also known as electric potential difference, is the measure of the potential energy difference between two points in an electrical circuit. It is measured in volts (V) and is responsible for the flow of current through a circuit.
Current is the flow of electric charge through a conductor. It is measured in amperes (A) and is the rate at which electric charges pass through a given point in a circuit.
Ohm's Law is used in a variety of real-life applications, such as designing and analyzing electrical circuits, calculating the power consumption of electronic devices, and determining the appropriate size of wires and resistors for a given circuit. It is also used in industries like telecommunications, power generation, and electronics manufacturing.
