In this article we talk about resistors in parallel, the equivalent resistance and the current divider rule for parallel connection of resistors. Let’s consider this circuit: In circuit 1 we have two ...

These are DC circuits, with resistors in series and parallel formations. You'll recall that series formations occur when resistors are connected along the same path, so they have the same current ...

That’s just not something I have on hand, and the series/parallel approach will get tiresome fast. Ages ago, I had read about trimming resistors by hand, but had assumed that it was the domain ...

Complex circuits may have some resistors connected in series, and some connected in parallel. For example, the following combination of resistors shows two resistors connected in series ...

Of course, now you have two 40 ohm resistors, but when you put them in parallel you get the 20 ohms you desire. You also used four times the amount of wire, but there’s no free lunch.

voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach uses sense resistors in series with the ...

Conversely, the higher the impedance (assuming voltage remains constant), the lower the current. Imagine two unequally sized resistors in parallel. The current flowing through one resistor depends on ...

In this circuit the following applies. When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. The currents in the branches of a ...

That’s the same law that first year electrical students apply to determine the value of one resistor that’s in parallel with another resistor. Let’s look at that first year problem, first. You have ...

Sometimes, it's the little things that are just so darn handy to have around. I'm often confronted with having to choose a parallel pair of resistors to get as close as possible to some non-standard ...
