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).
To figure the resistance of a substance in ohms, more information would be needed. Resistance is calculated by (resistivity)*(length)/(cross sectional area). <br /> First consider a wire conductor. Electrical resistivity is a property of the substance (it usually will vary with temperature). The thicker a wire is (larger cross sectional area) will lower the resistance.
