Question

Please answer both questions

99 V The graph shows the voltage across and the current through a single circuit element connected to an AC generator. Identify the circuit element, and justify your choice with a brief explanation 0.14 2.8 A 0 a) The element is a resistor. b) The element is an inductor. c) The element is a capacitor. d) The element could be a resistor or capacitor. e) The element could be a resistor or inductor. Write down the voltage and current equations as functions of time for the graph shown in the previous problem. Substitute in all appropriate values.

Answer 1

From the graph current is leading the voltage by a phase   $\frac{\pi}{2}$  

is a capacitor ! Element zat ao Sin [zat V = 0008 V = 9o Sin (78.5t) I = 208 Sin [78.5t + ]
