An Ac Source of Period T and Maximum Voltage V

question 42

Multiple Choice

An ac source of period T and maximum voltage V is connected to a single unknown ideal element that is either a resistor,and inductor,or a capacitor.At time t = 0 the voltage is zero.At time t = T/4 the current in the unknown element is equal to zero,and at time t = T/2 the current is I = -I_max,where I_max is the current amplitude.What is the unknown element?

• A) a resistor
• B) an inductor
• C) a capacitor
• D) an inductor or a capacitor
