Explanation Introduction: A purpose of the electrical resistance is a metric which opposes the electrical flow. The opposite amount is electrical conductance and is the ease with which an electrical current pass through. Electrical resistance shares with mechanical friction some conceptual parallels. The electrical resistance is measured with the unit Ohm ( Ω ) . The name of this unit is given in honor of the German Scientist George Simon Ohm who successfully studied the relationship between Resistance, voltage, and current through the conductor. Energy dissipation is defined as the power of consumption in time " t " and power is the product of voltage and current through the resistor. P=VI E=Pt =
