WebMar 24, 2024 · The standard equation of an instantaneous value of a sinusoidal wave is: V = V m sin (ωt + ϕ) V m is the maximum value V is the instantaneous value at time t. Calculation: Given alternating current equation is i (t) = 100 sin 100 πt Instantaneous value at t = 1/600 seconds is i = 100 sin 100 π (1/600) i = 100 sin π/6 i = 100/2 = 50 A WebOct 31, 2024 · Alternating current or AC refers to the rapidly switching of flow of a circuit repeatedly, measured in Hz, switches (cycles) per second.

WebApr 8, 2024 · An electric circuit produces power which is given by the expression, P= I V. Where, I – the current flowing through the circuit and V- Voltage across it. AC circuits always offer reactance, therefore there are two components of power, a power component because of the magnetic field and another because of the electric field. WebSince the current and the voltage both depend on time in an ac circuit, the instantaneous power p ( t) = i ( t) v ( t) is also time dependent. A plot of p ( t) for various circuit elements is shown in Figure 15.16. For a resistor, i ( t) and v ( t) are in phase and therefore always have the same sign (see Figure 15.5 ). WebAC produced by an electromechanical alternator follows the graphical shape of a sine wave. One cycle of a wave is one complete evolution of its shape until the point that it is ready to repeat itself. The period of a wave is the … cake shop silicon oasis
