How do I connect two DC power supplies in series?
February 14, 2025 639
To connect two DC power supplies in series, connect the positive terminal of the first power supply to the negative terminal of the second power supply to form a "daisy-chain" connection, where the series voltage is the sum of the voltages of the two power supplies. To connect two DC power supplies in series, proceed as follows: Note that the voltage of the load should be equal to or higher than the sum of the voltages of the two power supplies to prevent damage to the load or power supply. In addition, the load's rated...

If you want to measure current, voltage, etc., you need specialized measuring equipment. Analog and digital multimeters are usually used to measure current, but the circuit must be cut off and the multimeter and the circuit connected in series in order to make the measurement. However, it is not uncommon that it is not possible to disconnect the circuit in some cases. In addition, there is a danger of electric shock when the circuit is disconnected. In this case the clamp meter...

What is current? In this article, you will learn the difference between current and voltage, as well as the types of current and how to measure it. We all touch and use electricity on a daily basis. However, there are many things about electricity that you may not know. In this article, we will introduce you to the basics of electric current, the difference between electric current and voltage, and the types of electric current and how it is measured in an easy-to-understand...

What is the difference between an oscilloscope and a spectrum analyzer/signal analyzer?
February 14, 2025 351
We usually use time as a frame of reference, focusing on when certain specific events will occur. This includes electrical events. Oscilloscopes allow you to view the instantaneous value of a particular electrical event (or the voltage value of some other event converted by an appropriate transducer) over time. In other words, we can use an oscilloscope to view the waveform of a signal in the time domain. Fourier theory...
