The waveforms of alternating voltage is the graph between:

Correct answer: D. Voltage along y-axis and time along x-axis

  • A. Current and time
  • B. Voltage and time
  • C. Voltage and current
  • D. Voltage along y-axis and time along x-axis

Explanation

"Voltage along y-axis and time along x-axis," represents the waveform of alternating voltage. It shows how the voltage changes over time, with voltage values plotted along the vertical y-axis and time values along the horizontal x-axis. This graph typically displays a sinusoidal pattern, illustrating the alternating nature of the voltage signal in an AC circuit.

About Alternating Current

Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
