Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere.
( I ) Current flows on a wire or conductor like water flowing down a river from the Negative to the Positive.
( E ) Voltage is the difference in electrical potential between two points in a circuit.
( R ) Resistance determines how much current will flow through a component.
( P ) Power is the amount of current times the voltage level at a given point.

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance. Mathematically, it can be expressed as I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.

What is the formula of ohmslaw?
Ohm's Law states that, for a passive element, V (the voltage drop) is proportional to I (the current in the component), and the proportional constant is R (the resistance). Namely, V = R * I. For DC operations in a passive element, Ohm's Law is dealing with scalar quantities. For AC, V and I become vectors (phasors) for Ohm's Law to be valid. A passive element is an electrical component that does not have gain, voltage gain or current gain. Examples are resistors, capacitors, inductors, diodes, and transformers. An active element is one that has gain. Examples are transistors (MOSFET, bipolar, and JFET). A solar cell is an active element. Although Ohm's Law does not apply to transistors, the Law still can apply to the passive components of transistors, if we represent the transistor with passive elements and active elements. ======================================
