Time and Voltage

19

The vertical axis measures voltage. The distance along one small square represents 0.1 mV, and along one large square, 0.5 mV. You will need to memorize these numbers at some point, so you might as well do it now.

Amplitude of 1 mV

Vertical axis (millivolts)

Amplitude of 0.5 mV

0.2 seconds

0.2 seconds

Horizontal axis (seconds) 1 second

Both waves are one large square in duration (0.2 seconds), but the second wave is twice the voltage of the first (1 mV compared with 0.5 mV). The flat segment connecting the two waves is five large squares (5 × 0.2 seconds = 1 second) in duration.
