🤓 Based on our data, we think this question is relevant for Professor Lyuksyutov's class at TAMU.

The circuit shown in the sketch has an ac voltage source, a resistor and a capacitor connected in series. There is no inductor. the ac voltage source has voltage amplitude 900 V and angular frequency 20 rad/s. The voltage amplitude across the capacitor is 500 V. The resistor has resistance R = 300 Ω.

Does the source voltage lag or lead the current?
