How Much Waterproofing Do Everyday Electronics Really Have?

AI Thread Summary
Most everyday electronics, such as keyboards and calculators, lack significant waterproofing, making them vulnerable to spills and moisture. Devices like watches and automotive electronics typically have better moisture resistance due to their intended use. While some consumer electronics may offer drip resistance, they are not designed for prolonged exposure to water. Environmental factors, like temperature changes, can lead to moisture accumulation inside these devices. Proper care and storage can help mitigate moisture-related damage to electronics.

The multi-function displays we used in the Air Force were at least water resistant, so either that was one heck of a coffee spill, or it somehow worked its way into the inner electronics!

How much consideration is given for waterproofing most user electronics? I swim with my watch all the time, but if I spill something in my $79 Logitech keyboard, it's toast. Same with my $11 Casio calculator.

Watches, automotive electronics, air conditioning electronics, and possibly items to be operated outside are going to be about the only items that have moisture resistance. All the cellphones, music devices, etc... may be drip resistant. However, heating and cooling through the course of a day will draw moist air in through the seams where it may condense and accumulate. Keeping these items inside or warm will drive off moisture.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Two capacitors, etc.'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
