Ohm's Law can be rewritten in three ways for calculating current, resistance, and voltage. If a current I should flow through a resistor R, the voltage V can be calculated. First Version of the (voltage) formula: V = I Ã R. If there is a voltage V across a resistor R, a current I flows through it.
The ohm (symbol: Ï) is the SI unit of electrical impedance or, in the degenerate case, electrical resistance. measurement in ohms is the reciprocal of a measurement in siemens, the SI unit of electrical conductance. Note that 'siemens' is both singular and plural. The reciprocal of the ohm is also called the mho, from ohm written backwards.
