tarm with the correct definition
Assuming the vertical sensitivity control is set to 0.5 volts per division, and the timebase control is set to 2.5 ms per division, calculate the amplitude of this sine wave in volts peak
Answer:
Amplitude of sine wave in volts peak = 2.25 V
Explanation:
Given:
Vertical sensitivity control = 0.5 volts per division
Time base control = 2.5 ms per division
Find:
Amplitude of sine wave in volts peak
Computation:
Amplitude of sine wave in volts peak = 4¹/₂[volts per division]
Amplitude of sine wave in volts peak = 4¹/₂[0.5]
Amplitude of sine wave in volts peak = 4.5[0.5]
Amplitude of sine wave in volts peak = 2.25 V
