. Consider a device connected to an ac power supply. The current leads the voltage by 90°, with the equation for the current being: i(t) = (2.5 x 10-3 A) sin((6.00 × 10³ rad/s)t + T/2). (a) Based on the equation for the current, is the device an inductor or a capacitor? Justify your answer. (b) The reactance of the device is given as X? = 310N. If the device is a capacitor, determine the capacitance. If the device is an inductor, find its inductance. (c) Find the maximum voltage, and using this write down the voltage equation for the system. Find the value of the voltage at t = 1.5s.

2. Consider a device connected to an ac power supply. The current leads
the voltage by 90°, with the equation for the current being:
i(t) = (2.5 x 10-³ A) sin((6.00 × 10³ rad/s)t +1/2).
(a) Based on the equation for the current, is the device an inductor or
a capacitor? Justify your answer.
(b) The reactance of the device is given as X?
= 3102. If the device is a
capacitor, determine the capacitance. If the device is an inductor,
find its inductance.
(c) Find the maximum voltage, and using this write down the voltage
equation for the system. Find the value of the voltage at t = 1.5s.
