Calculate the total resistance of the circuit, or Rt. Rt depends on the number of resistors and how they are connected. If one resistor exist, Rt is the value of that resistor. If several resistors exist, determine if they are connected in series or parallel and use the following formula:...
In addition to these electrically neutral molecules floating about are molecules that carry a net positive or negative electrostatic charge. These are calledions, and it can be handy to have an ion tester on hand to measure negative ions in particular; one everyday example is a household smoke ...
In a single-phase buck converter, there is only one power stage and one output; hence, one point to measure at. In a multiphase buck converter, there are multiple outputs that are connected electrically. Take a four-phase buck for example: a four-phase buck ...
Calculators may show up anywhere in our lives that numbers do -- from calculus class to restaurants. See how calculators work.
We measure the potential difference in volts (which has units of joules per coulomb). The voltage in an electrical circuit controls the current in combination with the resistance. The voltage can be looked at as exerting an electric force on a positive charge (or a negative charge in the opp...
Avoid Right-Angle Turns: Use 45-degree angles or rounded corners to reduce impedance discontinuities. Power Delivery Network Impedance Yourpower delivery network (PDN)shows capacitive impedance at low frequencies and reduces the resistance of the power bus, load components, and ground path at ...
I'm designing an input filter for a power converter and the output impedance of the filter needs to stay comfortably under the input impedance of the converter, which looks like a 15 uH inductance at its operating point. Staying under 15 uH is a squeeze, but this one seems to be a good...
This can become a problem if the DC resistance of the load coil is high. To combat this one may wish to use a larger capacitor than inductor, since a metalized polyester capacitor’s parasitic resistance tends to be smaller than a large coil’s. ...
What is the basic principle of oscillation? Oscillation is defined asthe method of repeating variations in time of any sum or measure of its equilibrium value. It is also possible to describe oscillation as a periodic variation of a matter between two values, or of its central value. ...
Ohms are a unit of measure for the impedance or resistance in a piece of gear.To understand impedance, imagine a hose plugged up with gunk slowing the water flow. If you want more water to come out, you have to increase the amount of water at the faucet to increase the water pressure...
