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 symbol for an ohm is Ï or W. One ampere is the unit of measurement of electrical current produced in a circuit by 1 volt acting through a resistance of 1 ohm. With an ordinary coil of around 10,000 ohms resistance, the most powerful arc would be produced with about 12,000 alternations per second. An ohm is a unit of measurement of electric resistance.
