The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.
Explanation:
- Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
- To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
- A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.
Answer:
False
Okay now I have to go to my school--
Answer: Hello your question lacks some details attached below is the missing detail
answer :
a) True , B) False C) True D) True
Explanation:
a) True ; The critical section cannot be executed by more than one process at a time
b) False : The code does not satisfy the progress condition, because while loops are same hence no progress
c ) True : The code satisfies the bounded waiting condition, because of the waiting condition of the while loop
d) True : No matter how many times this program is run, it will always produce the same output, this is because of the while loop condition
Answer:
True
Explanation:
The Federal communications commission (FCC), is responsible for evaluating the effect of radio frequency and electromagnetic radiations and emissions on the consumers of products which make use of these frequencies and radiation energy. Devices such as cell phones are not allowed to emit radiation higher than a certain safe standard or frequency, set by the Federal communications commission.
The Federal communications commission also provides bulletins and publications that present safety information and guidelines for industries and consumers involved with radio frequency and electromagnetic radiation.
