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).
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.
