Supercapacitor vs Battery - Comparison and Case Study There is a long debate that Supercapacitors will overrule the battery market in the future. A few years back when Supercapacitors were made available, there was a huge hype about it and many expected it to replace the batteries in commercial electronic products and even in Electric Vehicles. But, nothing like that actually happened, because both Supercapacitors and… |

12V Audio Power Amplifier using TIP35C – Class A Amplifier Loudspeakers are heavy loads, and they normally require high current to be driven which is provided by an external circuit. This is because sometimes the produced sound output, let's say from a microphone or the pickup coils of the guitar, do not produce high current high amplitude output, therefore, it is not suitable to drive a loudspeaker. This is why we have something… |

What is PoE and How Power over Ethernet Works Internet connectivity has become necessary nowadays as almost every electronic device needs an active internet connection to work properly. Although most of the devices have Wi-Fi connectivity options, but many devices and network routers still used Ethernet ports and cables to connect with the wired internet line. We previously learned about how data can be transferred over… |
