For your bass example, we can devise a following scenario. If you have a 1A power supply, it can''t provide a peak current of 2A which an amplifier may need under heavy transient. But if you put a capacitor in between the power supply and amplifier, the power supply ...
Learn MoreWhere E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.
Learn MoreThe charge stored in the capacitors goes towards the rest of the system (that is, to where the power supply is connected) and, essentially, keeps the system running for a very short time longer. But as the supply voltage decays, so does the …
Learn MoreFind step-by-step Physics solutions and your answer to the following textbook question: A capacitor used to provide steady voltages in the power supply of a stereo amplifier charges rapidly to $35 mathrm{~V}$ every $1 / 60$ second. It must then hold that voltage ...
