As an example, assume Rt is 300 ohms. Calculate the total inductance of the circuit, or Lt. Lt depends on the number of inductors and how they are connected. If only one inductor exist, Lt is the value of that inductor. If several inductors exist, determine if they are connected in se...
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 ...

To understand the process, let's first look at what inductance is. The illustration on this page is helpful. Here you see a battery, a light bulb, a coil of wire around a piece of iron (yellow), and a switch. The coil of w...
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...
An alternative approachfor this type of current sensing technique is touse the PCB trace as shunt resistor.Since the copper trace of a PCB offer very small resistance, one can use the trace to measure the current. However, in such an alternative approach, several dependencies are also a ...
An RL circuit time constant is a measure of the rate at which current flows through a circuit. It is defined as the time it takes for the current to reach 63.2% of its maximum value in an RL circuit, which contains a resistor (R) and an inductor (L). 2. How is the time constant...
return when traveling in the ground plane. Ideally, the path of least reactance in a star, point-to-point, or multipoint topology should lie directly beneath conductors in your board. This will ensure your circuits have minimized loop inductance and will have the least susceptibility to ...

A junction box does a fine job of housing the EHT components. [Image 1] displays the junction box which houses my machine's Coolidge tube, its lead shield, the voltage multiplier and a 1.8 billion ohm resistor to measure the anode voltage. A 90kV this resistor will leak the 50uA needed...
