Alternating Currents and Voltages

Phase Relation in Pure Resistor

Phase Relation in Pure Resistor: Phase Relation in Pure Resistor – When a sinusoidal voltage of certain magnitude is applied to a resistor, a certain amount of sine wave current passes through it. We know the relation between υ(t) and i(t) in the case of a resistor. The voltage/current relation in case of a resistor

Measuring the Sine Wave

Measuring the Sine Wave: As the magnitude of the waveform is not constant, the Measuring the Sine Wave can be in different ways. These are instantaneous, peak, peak to peak, root mean square (rms) and average values. Instantaneous Value: Consider the sine wave shown in Fig. 4.12. At any given time, it has some instantaneous

Sine Wave Equation

Sine Wave Equation: A Sine Wave Equation is graphically represented as shown in Fig. 4.10(a). The amplitude of a sine wave is represented on vertical axis. The angular measurement (in degrees or radians) is represented on horizontal axis. Amplitude A is the maximum value of the voltage or current on the Y-axis. In general, the

Phase of Sine Wave

Phase of Sine Wave: Phase of Sine Wave – A sine wave can be measured along the X-axis on a time base which is frequency-dependent. A sine wave can also be expressed in terms of an angular measurement. This angular measurement is expressed in degrees or radians. A radian is defined as the angular distance

The Sine Wave

The Sine Wave: Many a time, alternating voltages and currents are represented by a sinusoidal wave, or simply a sinusoid. It is a very common type of alternating, current (ac) and alternating voltage. The sinusoidal wave is generally referred to as a sine wave. Basically an alternating voltage (current) waveform is defined as the voltage
