I don't understand what this problems means....do I need some more equations?(adsbygoogle = window.adsbygoogle || []).push({});

The voltage in a circuit is given in SI units by V = 80sin200t. What is the voltage at t = (1/60) s?

A. 0V

B. 15V

C. 80V

D. -15V

Can you even have a negative voltage? I guess I just don't understand the complexities of this problem.

Also guys....Do you guys know what the equations needed to help find charge and voltage through capacitors in series and parallel??
