Resistors Explained: Ohm’s Law and Electrical Resistance
This video explains the role of resistors in electronic circuits and how Ohm’s Law defines the relationship between voltage, ...
Offline power supplies that drive loads of 200W and more require inrush-current limiters. Unrestricted inrush currents can reach hundreds of amperes, which may damage the line rectifier, open the fuse ...
The B5303 current-to-voltage transducer converts a primary current (up to 200 A, 50 to 400 Hz) to a programmable 0- to 10-V ac control or instrument voltage. It ...
When an electric current passes through the body, it can cause three main effects: When it comes to current, DC becomes hazardous at around 130 milliamps (mA)—a seemingly small amount, especially ...
When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...
There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
An electric current is a flow of charged particles. A source of energy, such as a cell or battery, is required to make the free electrons move in one direction. Electrons are negatively charged ...
Some years ago, one of the fundamental electronic instruments was the laboratory curve tracer. A CRT display would sweep out terminal behavior (current versus voltage) from which you could derive ...
One of the most productive new approaches to power quality is immunity testing — making sure that loads can tolerate common disturbances without additional filtering or support. This kind of testing ...
Voltage unbalance can be a common steady-state power quality problem that is harmful to 3-phase electric motors. The condition can cause overheating and insulation damage. The cost of damage to motors ...
