How to Read an Oscilloscope - GCSE and A Level Physics

This video explains how to read an oscilloscope. Oscilloscopes are often quite old and can be tricky to decipher. However it's not as bad as you think! Oscilloscopes essentially displays a graph that changes in real time. The y-axis is potential difference (voltage) and the x-axis is time. An alternating current source will produce a sinusoidal wave signal on an oscilloscope whereas a direct current will produce a flat line. For an alternating current source, the distance between two peaks is the time period of the wave, not the wavelength. The time base and the voltage scale of the oscilloscope can be altered in order to see the waveform more clearly.
