I know that current is generated by charges moving in an electric field caused by other nearby charges is this phenomenon called Ohm's Law? I'm a bit confused.
Pengwuino said:Ohm's law is a series of equations dictating the relationship between voltage, resistance, current, and power in DC circuits.

Tide said:I'm not sure exactly what you have in mind but if you have a net movement of charge then you have, by definition, electrical current. The presence of an electric field may cause the flow of current to change (either increase or decrease or remain the same in some circumstances).
Do you want to elaborate on what you mean?

Ohm's Law is a fundamental principle in physics that describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage applied to it, and inversely proportional to the resistance of the conductor.
Ohm's Law is directly related to generating current because it explains the relationship between voltage, current, and resistance in an electrical circuit. By applying a voltage to a conductor, the flow of current can be generated and controlled based on the resistance of the conductor.
The current generated in a circuit is influenced by the voltage applied, the resistance of the conductor, and the type of material used in the conductor. Other factors such as temperature and length of the conductor can also affect the current generated.
To calculate the current in a circuit using Ohm's Law, you can use the equation I=V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms. By rearranging the equation, you can also calculate voltage or resistance if you know the other two values.
Ohm's Law is a general principle that applies to most electrical circuits, but it does have limitations. It assumes that the conductor is a perfect conductor and that the temperature remains constant. In real-world applications, there may be variations due to imperfect conductors, changes in temperature, and other factors.
