Product description
As the current increases, the voltage across the arc discharge gap decreases, tending to a certain constant value at high current values. The electric arc was connected to the network in series with some ballast resistor. The current-voltage characteristic of the dependence of voltage on current of this value is shown in Figure 11.13. Complete the following tasks: 1. Construct the current-voltage characteristic of the arc without a ballast resistor. 2. Using the obtained current-voltage characteristic of the arc, determine the maximum resistance of the ballast resistor at which the blower can burn at source voltage U0=85V.
