Different Types of Ships its Parts and Characteristics of its Parts. As a result, one watt will be equal to the volt-ampere result of one-volt times one-ampere (one watt is the rate of consuming energy at one joule per second). An alternating current (AC) is an electrical current that regularly reverses direction and changes its value constantly with time, contrary to DC current, which travels only in a single direction. Research shows that a social-emotional learning curriculum can lead to improved academic performance. View the circuit as a schematic diagram, or switch to a lifelike view. In that case, the power dissipated in watts is given by any of the following generalized equations: P=V\times I=R\times I^{2}=\frac{V^{2}}{R}. The fundamental terminologies used in ac circuits are introduced, and a number of custom-written VIs, considering both single-phase and three-phase ac circuits, are provided. Protocol studies revealed that In electrical circuits energy is In addition, capacitive reactance depends on the capacitance of the capacitor in Farads and the frequency of the AC waveform. Step 2: Circuits. If load is increased beyond this point, the motor will stall and come to a rapid stop. The sinusoidal waveform or sine wave is the most commonly used AC waveform in circuit theory. A resistor is a device that controls current in electric circuits.
