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).
Impedance, which is given the letter Z, in a pure ohmic resistance is a complex number consisting only of a real part being the actual AC resistance value, ( R ) and a zero imaginary part, ( j0 ). Because of this Ohmâs Law can be used in circuits containing an AC resistance to calculate these voltages and currents.
