In electrical or electronic circuits, a characteristic of a material that opposes the flow of electrons, measured in ohms (Ω). Calculated byb y the formula R=E/I, where E is the voltage, and I is the current flow in amperes, through the circuit. Resistance results in loss of energy in a circuit dissipated as heat. Conductance, is the reciprocal of resistance.
