Ohm's law is the most fundamental physical law in elläran. It describes the relationship between the electrical voltage, electrical resistance and electrical current. Ohm's law is used in all work with electricity.
The law is named after the German physicist Georg Simon Ohm (1789-1854). In 1827, he presented evidence of the relationship between voltage, current and resistance.
Ohm's Law says that the current flow (flow of electrons) is directly proportional to a voltage difference (potential difference) and inversely proportional to the wire resistance (resistance). One ohm is the resistance through which one volt maintains a current of one ampere.
The voltage becomes U, current I and resistance R.
U = I * R I = U / R R = U / I
Since electric power P, measured in watts (W), is a result of current and voltage also Ohm's law:
P = I 2 * R I = P / U R = U 2 / P D = P / I

Ohm's Law is the most basic law within minutes Electricity. It define the relationships Between Voltage, electric current, and electric resistance.
Ohm's Law is useful in any kind of electronics and electric work.
The law is named after the Germantown physicist Georg Simon Ohm (1789-1854). In the year 1827 he proved the relationship Between Voltage, Current, and Resistance.
Ohm's Law states thats the current (flow of electrons) is Directly Proportional to the voltage drop (potential Difference) and inversely proportional to the Drivers resistance. One ohm is the resistance value through Which one volt Will Maintain a current of one ampere.
The voltage (electro motivated force) ice-designated E (or V), the current I and the resistance R.
E = I * R I = E / R R = E / I
Since electrical power P, measured in wattage or watts (W), is a result of current and voltage Ohm's Law also "Gives:
P = I 2 * R I = P / E R = E 2 / P E = P / I
