For students, college students or the hobby of electronics with the law must know this one, if not, must know .. In 1826, a German physicist named berkembangsaan Georg Simon Ohm investigate the relationship of proportionality between V and I. Ohm experimented with forming an electrical circuit and is equipped with various electrical components.
The graph shows that the relationship between V and I form a straight line inclined to the right up through the point of origin. If the slope of this graph is called a barrier (given the symbol R), makia the relationship between voltage V and the strong current I can be expressed in the formula: V = I. R R = resistance (Ω) I = current (I) V = Voltage (V) To further facilitate our understanding of Ohm's law in this circuit let us consider the following:

Seen that the above circuit has V = 9 volts, R = 1 kilo Ohm, then current = V / R = 9 / 1000 = 9mAmpere. If we replace the value of R becomes larger or smaller then we will be able to draw the conclusion that the current generated will be greater if the value of resistance in the circuit gets smaller and vice versa with the assumption that the voltage value tetep.
