Now consider an AC circuit with two voltage sources. Here, magnitude, polarity, and phase angle are used to find the equivalent voltage. Electrical Polarity in AC Voltages In the first figure, both sources have the same polarity. Hence, the equivalent voltage is the addition of both. But these are the polar form—First, we need to convert this polar form into a rectangular form. And it will be—Now, the equivalent voltage is the addition of each of the X-components and Y-components (i.e. )—Ag

What is Electrical Resistance?Resistance (also known as ohmic resistance or electrical resistance) is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).The larger resistance, the greater the barrier against the flow of current.When the potential difference is applied to a conductor, the current starts flowing, or the free electrons start moving. While moving, the free electrons collide with the atoms and
