Question

The voltage, V, in volts, applied to an electric circuit can be modelled by the equation V=167sin(120πt)V=167 \sin (120 \pi t), where t is the time, in seconds. A component in the circuit can safely withstand a voltage of more than 120 V for 0.01 s or less. a) Determine the length of time that the voltage is greater than 120 V on each half-cycle. b) Is it safe to use this component in this circuit? Justify your answer.
