Ohm's Law

Ohm's Law

Ohm's law recognizes three formulas for the calculation of current, resistance and voltage.

If at the resistance R is the voltage U, there flows the current I through the resistor R.

Flows through a resistance R the current I, is due to R the voltage U.

Should through a resistance R the current I flow, the voltage U has to be calculated.

The resistive triangle can be used as an aid to the different formulas of Ohm's law to be determined. The value to be calculated, is highlighted. With the two other values, the result is going to be calculated.
