Questions & Step-by-Step Solutions
In a simple AC circuit, if the voltage is given by V(t) = 10 sin(100t), what is the peak voltage?
Step 1: Identify the given voltage function, which is V(t) = 10 sin(100t).
Step 2: Look at the sine function in the equation. The general form of a sine function is A sin(Bt), where A is the peak voltage.
Step 3: Find the coefficient of the sine function in the equation. In this case, the coefficient is 10.
Step 4: Conclude that the peak voltage is the value of this coefficient, which is 10 V.
Peak Voltage – The peak voltage in an AC circuit is the maximum value of the voltage waveform, represented by the coefficient of the sine function in the voltage equation.
AC Voltage Representation – Understanding how AC voltage is represented mathematically, particularly in the form V(t) = V_peak * sin(ωt), where V_peak is the peak voltage.
