If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

We define the properties of parallel and complex circuits. Unit 5 Segment H: Parallel and Complex Circuits We define the properties of parallel and complex circuits. We examine how to find the total ...

An ammeter is always connected in series with the component whose current you want to measure. This means it is placed ...

Stepper motors contain coil windings that require resistance measurements. Measuring resistance in a production environment often requires some special circuits that minimize errors. Resistance is ...

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

In Part 1 of the Electronics for Kids series, we looked at LEDs; in Part 2, we explored capacitors; and in Part 3, we took an in-depth look at electrical measurements. In this article, we will focus ...

The “trimpot” is the standard solution to the analog designer’s occasional need to fine-tune a resistance in a precision circuit. But this old standby isn’t always available. For example, in some ...
