Potential Difference#!#Current

The group of solar cells connected in specific pattern to produce definite potential difference and current is known as____.

For an AC circuit the potential difference and current are given by V = 10 sqrt(2) sin omegat (in V) and i = 2 sqrt(2) cos omegat (in A) respectively. The power dissipated in the instrument is
