Basic Definitions Perhaps you need to know what AC voltage to apply to the circuit, given that the current in the circuit needs to be 10 A. Okay...there is a slight mistake. Website showing example of use of imaginary or complex numbers: Application to Electrical Engineering: First, set the stage for the discussion and clarify some vocabulary. One of the most important uses is the use of complex numbers in phasor analysis. INTEGRATION OF CALCULUS, ITS PURPOSE, APPLICATIONS AND ITS IMPORTANCE IN MATHS. Resource. It has forever transformed the world of electronics. A single complex number puts together two real quantities, making the numbers easier to work with. RELATION BETWEEN UNIT VECTOR AND UNIT CIRCLE. We saw in the previous page that the voltage across a capacitor is delayed relative to the current: when a voltage source is first connected to an RC circuit, the current through the capacitor reaches its maximum value right away, but the voltage drop gradually increases toward the maximum value. Application: You are designing a simple AC circuit and you need to know the voltage across different parts of the circuit. Division of surds. Reactance and Angular Velocity - important when creating alternating currents 11. VECTORS: Significance &application of Cross product and dot product. This seems odd at first, as the concept of using a mix of real and ‘imaginary’ numbers to explain things in the real world seem crazy! Imaginary numbers use the unit of 'i,' while real numbers use '1,' and complex numbers combine both real and imaginary numbers for use in a variety of mathematical calculations.

Integrated circuit (IC) is the most significant technological development of the 21st century if I may say. Conjugates are used when dividing complex numbers, so that the denominator has no imaginary numbers. Before we see how complex numbers can help us to analyse and design AC circuits, we first need to define some terms. TRIGONOMETRIC, EXPOTENTIAL & COMPLEX FORMS OF EXPRESSING THINGS.
