Do modern radios and power supplies require grounding for safety?

In the circumstances that you talk about with the help of the picture, the power supply is grounded through the mains power feed. The power supply can be considered safe because if a live wire comes adrift for example inside the power supply and touches the chassis, the protection circuit, often a fuse, should blow, avoiding any risk …

Common ground and why you need one

At that time, a power supply had a power output terminal and a return terminal. The engineers decided that the chassis could be considered as a big, fat wire. So they connected the return wire of each of the power supplies to the chassis. Then every circuit wherever it was located would have a wire connected to the chassis for the …

Battery Backup Circuit: A Comprehensive Guide in Making One

12V power supply with battery backup circuit . We''ll use a 12V power supply to make a battery backup circuit for our first DIY project. When there are power-supply voltages, the load shifts to that main supply as the battery goes into automatic charging mode. However, when there''s no mains supply, the circuit will automatically …

The idea is that it''s best to keep the difference between the two points at the same potential so that there is no difference. No difference, no volts, no current, happy circuit. 112 votes, 28 comments. 222K subscribers in the …

power supply

No part of the cars electrical system is deliberately connected to the earth, so when you touch the cars body and the earth at the same time there is really nowhere for current to go. The voltage between different parts of the cars chassis will normally be a small fraction of the (already low enough to be safe) battery voltage.

Why is Floating circuits in DC Power Supplies safe?

Even if the lab supply''s AC mains input has a large common-mode voltage for some reason (eg hooking it to a 208v circuit or something), it won''t appear at the floating output due to the isolation - you''d need to connect your dangerous equipment between one of the DC output terminals and either mains safety earth or the supply''s ground terminal ...

Purpose of the Power Supply Ground terminal?

So, for instance, ground to pin 1 (the center terminal), internal battery to pin 2, and pin 3 goes to circuit. If things are wired up so + is on the center, you are cutting power from the battery negative to ground. If wired so - is center, you are cutting power from the battery positive to Vcc.
