A series circuit consists of an oscillating voltage source (@=20 rad/s), a 302 resistor and an unknown component (R, L or C in the “?" box) as shown. 7. If the voltage is observed to lead the current, identify the type of the unknown component. 8. With the emf amplitude set to 150V, the current amplitude is observed to be 3A. Find the value of the unknown component. 9. A second unknown component is added to the circuit (in series again) and the current increases to 5A (without changing the emf amplitude). Find the value of this new component.
