The Voltage V Across a 1 μF Pure Capacitor Varies

question 2

Multiple Choice

The voltage v across a 1 μF pure capacitor varies with time t according to the equation v = 16 sin 2000t V. The current through the capacitor will thus be:

• A) i = 16 sin 2000t mA
• B) i = 16 sin (2000t + 90º) mA
• C) i = 32 sin 2000t mA
• D) i = 32 sin (2000t + 90º) mA
