To determine the peak voltage, we need to find the maximum value of the sine function. In this case, the maximum value of sin40πt is 1, so the peak voltage is 4V.
To find the frequency, we need to look at the coefficient of t in the function. In this case, the coefficient is 40π. The frequency can be calculated by dividing this coefficient by 2π.
frequency = 40π / 2π = 20 Hz.
An AC voltage across a resistor in a radio circuit in volts is given by: V=4sin40πt
