Step 3: If found, it sends the file to the PHP interpreter (since PHP is an interpreted language), which checks for requested data into the database. PDF Version. (T/F). and more. As the load and slip are increased beyond full-load torque, the torque will reach a maximum value at about 25% slip. output voltage before the load is applied. But in the real world, we always have a combination of the components mentioned earlier, which includes resistance as well. Students can use it to gauge their level of understanding of circuits and to reflect on what still needs to be understood. Another special example is that the current and voltage are out of phase by 90; this is an essential case because there is no power loss in the circuit when this occurs. AC Current.
