This chapter covers many basic principles and important concepts that carry a lot of weightage and also importance, considering future studies also. This ratio of 3:1 (3-to-1) simply means that there are three primary windings for every one secondary winding. II. An open circuit would break the flow of electricity between power and ground. Reactance also blocks the current flow, but the value of reactance is not a fixed amount for one capacitor or inductor compared to a resistor with a fixed value of resistance. Sometimes we need different voltage levels in the same circuit. AC GENERATION Basic AC Theory The induced voltages add in series, making slip ring X (Figure 1) positive (+) and slip ring Y (Figure 1) negative (-). The wires connected to the brushes of a generator are designated and wound armatures are probably the most commonly used because they are designed for moderate voltages and moderate currents. In an AC induction motor, as slip increases from zero to ~10%, the torque increases linearly. In DC circuits, there is no conception of inductive and capacitive reactance. Where \theta =\theta _v-\theta _i , and by placing in the above equation we have: p=\frac{V_mI_m}{2})(cos(\theta )-cos(2\omega t+\theta )), \frac{V_mI_m}{2}=\frac{V_m}{\sqrt{2}}\times \frac{I_m}{\sqrt{2}}=V_{RMS}\times I_{RMS}.
