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).
OHM: This range of settings allows the multimeter to be used as an ohmmeter to measure the resistance of a circuit component. The scale settings range from 200 (ohms) to 20 M (megohms). There is also a setting with a musical note above it; this setting will provide an audible tone when the resistance of a component is less than 30 .
