How do you calculate the power absorbed by a capacitor?

You find the power by multiplying the current and voltage, resulting in the bottom-left graph shown here. Finally, you can find the energy by calculating (½)C[vC(t)]2. When you do this, you get the bottom-right graph shown here.

What is the formula for capacitor?

The governing equation for capacitor design is: C = εA/d, In this equation, C is capacitance; ε is permittivity, a term for how well dielectric material stores an electric field; A is the parallel plate area; and d is the distance between the two conductive plates.

How to select a transformer for 5V DC power supply design?

This means we should select the transformer with a secondary voltage value equal to 9V or at least 10\% more than 9V. From these points, for the 5V DC power supply design, we can select a transformer of current rating 1A and a secondary voltage of 9V.

How do you calculate the generated voltage of a DC machine?

Generated voltage of a DC machine is a linear function of the flux per pole, so it is also nonlinear with respect to the field current. n1 < n2 < n3 So if we have two voltages at two different speeds, with the flux per pole held constant: If we know generated voltage at one speed we can calculate generated voltage using the same DC

Can I make a 5V DC circuit without a rectifier?

Without the rectifier circuit, it is not possible to have the required output 5V DC voltage. This circuit comes in nice integrated packages or you can make it using four diodes as well. You will see how we design it in later sections.

Do I need a DC or DC power supply for computing?

Most electronic circuits require a DC power supply. Chances are you have one at home already, and can use it for physical computing projects. The most common operating voltages for microcontrollers and digital processors are 5V and 3.3V. You can find power supplies in many voltages, but 5V and 12V are common.
