Zettaohm (zΩ) Sainmhíniú aonaid

The siemens (S) is the SI derived unit of electric conductance and admittance, also known as the mho (ohm spelled backwards, symbol is ℧). It is the reciprocal of resistance in ohms (Ω).

The power dissipated by a resistor may be calculated from its resistance, and the voltage or current involved. The formula is a combination of Ohm's law and Joule's law where: P = V ∙ I = ^V2⁄_R = I² ∙ R. Where:

• Is é P an Power

• Is é r an fhriotaíocht

• Is é V an voltas trasna an fhriotóra

• Is mise an sruth tríd an bhfriotóir

A linear resistor has a constant resistance value over all applied voltages or currents. Many practical resistors are linear over a useful range of currents. Non-linear resistors have a value that may vary depending on the applied voltage (or current). Where alternating current is applied to the circuit (or where the resistance value is a function of time), the relation above is true at any instant but calculation of average power over an interval of time requires integration of instantaneous power over that interval.
