Although the result may seem like something out of a freak show at first, applying the definition of the exponential function makes it clear how natural it is: ex = lim n → ∞(1 + x n)n. When x = iϕ is imaginary, the quantity (1 + iϕ / n) represents a number lying just above 1 in the complex plane.

A capacitor is an electrical component used to store energy in an electric field. It has two electrical conductors separated by a dielectric material that both accumulate charge when connected to a power source. One plate gets a negative charge, and the other gets a positive charge. A capacitor does not dissipate energy, unlike a resistor.

When capacitors are placed in parallel with one another the total capacitance is simply the sum of all capacitances. This is analogous to the way resistors add when in series. So, for example, if you had three capacitors of values 10µF, 1µF, and 0.1µF in parallel, the total capacitance would be 11.1µF (10+1+0.1).
