Power Resistance
What is the proper diet and the resistance of a shunt resistor connected to an amplifier 13, 50 volts DC?
also What is the proper feeding of the potentiometer must be used for variable current output from zero to 13 amps?
Part 1, depends on the amount who wishes to draw resistance. You can use a resistance of 10,000 ohms and the need for a 4 / 1 watt resistor or a resistance of 10 ohms and dissipate 250 watts. Part 2, A potentiometer maneuver remains a problem, because when you mark on the top, a small settlement will take care of all courts. Moreover, waste supply. For example, a pot 50 ohm 1 A or dissipates 50 watts, but when at the top of its range, which is 13 SAP in the context of liquidation, which means it must be evaluated by 13 ² * 50 or 8500 watts! A pot of 10 ohms will dissipate 5 amps or 250 watts. In the development of 13 amps, should be valued at 13 ² * 10 or 1700 watts. A variable resistor in series will not be able to reduce the current zero ..
