Particles that are free to move, if positively charged, normally tend towards regions of lower electric potential (net negative charge), while negatively charged particles tend to shift towards … See more

Given a charged object in empty space, Q+. To move q+ closer to Q+ (starting from $${\displaystyle r_{0}=\infty }$$, where the See more

The electric power is the rate of energy transferred in an electric circuit. As a partial derivative, it is expressed as the change of work over time:
$${\displaystyle P={\frac {\partial W}{\partial t}}={\frac {\partial QV}{\partial t}}}$$ See more
