Solution

To answer this question, we need more information about the sine waveform such as the frequency or the period. The voltage at a specific time in a sine waveform is calculated using the formula:

E(t) = Emax * sin(2πft + φ)

where:

  • E(t) is the voltage at time t,
  • Emax is the maximum voltage,
  • f is the frequency,
  • t is the time, and
  • φ is the phase angle.

Without the frequency or the period of the waveform, we cannot calculate the voltage at t = 3.8ms.
