An Ac Source of Period T and Maximum Voltage V

question 41

Multiple Choice

An ac source of period T and maximum voltage V is connected to a single unknown element. 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
• E)More information is needed to identify the element.
