Building Trust - Trust is key to coaching. The supervisor and employee relationship must have some level of trust for coaching to work. A mutual interest in the success of the other is critical. Trust can begin to develop through open, honest feedback and respect.
A resistor at constant temperature (ohmic conductor). Current is directly proportional to potential difference. Doubling the potential difference doubles the current in the circuit. The resistance remains the same. Plotting a graph of potential difference against current gives a straight line passing through the origin (0,0).
Ohms definition, the standard unit of electrical resistance in the International System of Units (SI), formally defined to be the electrical resistance between two points of a conductor when a constant potential difference applied between these points produces in this conductor a current of one ampere.
