Answer #1
  1. w fds) = wr fqs) 290

  1.   V=V°Sin(ῳt), V°= max voltage

     As per question requirement, V = V°Sin (ῳt +90)

     Hence the equation is V=V°Cosῳt

    A three phase induction motor draws a starting current which is five times the full load current with direct on line starting, while developing twice the full load torque. Q2.1. Based on the two facts that starting current is proportional to the applied voltage and that the starting torque is proportional to the square of the applied voltage, determine voltage (as a per cent of rated voltage) required to obtain a starting torque equalling the full load torque.

    I am currently trying to figure out the experiment below. Please complete Table 1 with an explanation, I appreciate it thank you!  Promise to give thumbs up! Introduction The phase differences between the output voltage, the voltage across the inductor, the voltage across the capacitor, and the voltage across the resistor will be examined at resonant frequency. The voltage and phase relationship will also be examined for frequencies above and below resonance. Theory An inductor, a capacitor, and a resistor are...

    Learning Goal: To use the node-voltage method to solve circuits with branches containing only a voltage source. The node-voltage method is a general technique for solving circuits. Fundamentally, it involves writing KCL equations at essential nodes. When the circuit contains a dependent source, you must write a constraint equation for each dependent source, in addition to the KCL equations. When the circuit contains one or more voltage sources that are the only components in branches connecting two essential nodes, the...
