R Resistance in Ohm. The other derivations are based on this one but this ones pretty because it emphasizes the dependence of the current to the voltage. Formula to convert volts to resistance Ohm Law.
The voltage is always proportional to the current that is the law.
Yes VIR is the correct expression for Ohms Law. Looking at the Ohms Law. Current calculation Ohms law formula I V R Current Ampere Voltage V Resistance O Resistance calculation Ohms law formula. Ohms Law is a formula used to calculate the relationship between voltage current and resistance in an electrical circuit.
