	Answer: C) w, R, & C Right, all three variables in the system affect the phase. Also you may have noticed that this phase shift causes the current to 'lead' the voltage, that is the current's crests come before the voltage's. This is a positive phase shift. Press start on the browser applet. Go ahead and vary the capacitance. Notice that as the capacitance gets small, then the current diminishes as well. You'll also see that as the capacitance gets smaller, the phase gets bigger. The RC circuit follows the system of equations to the left. Press Next to move on to the LR Circuit.
