Electronics Guide Part 1 - the Basics

If a piece of wire had truly no resistance then the voltage or potential difference across it would be "shorted out" making the votage = 0. As stated above no voltage = no current. All these things are linked together by the most common formula in ...223 Physics Lab: Ohm's Law & Kirchhoff's Rules

Figure 1. For resistors in series, the current through each resistor is identical. If the resistances and current are both known, the voltage drop across each resistor may ... 3 and is given by the following formula: The rules for determining the sign ...How a 1:4 Guanella-Balun (Current-Balun) Operates

It is important to put out ... In Figure 5, we are not concerned with the transmitter or its output-resistance. All we really care about is that there is Zin and a voltage across it; we’ll call that voltage “V”. Recall that power going into a resisto ...The x86 Power Myth Busted: In-Depth Clover Trail Power Analysis

Clip the voltage input leads coming from the battery to the PCB, toss a resistor inline and measure voltage drop across the resistor to calculate ... spikes in voltage in these circuits, you can figure out what components on a smartphone or tablet ...Circulating currents: The warnings are out

If the current in the ground connection is large enough or if it changes fast enough, it generates a significant amount of voltage. That voltage might ... It will then take many months if not a year to figure out the problems and redo the circuit.
