Wait Doctor Brenner is coming back?!?! Wait omg when??
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.
Explanation:
in c++
#include<iostream.h>
#using namespace std;
main()
{ float x,y,z,r, phi, theta;
cout<<" enter the value of x";
cin>>x;
cout<<" enter the value of y";
cin>>y;
cout<<" enter the value of z";
cin>>z;
r = (sqrt(pow(x,2) + pow(y, 2) + pow(z, 2)));
phi = (asinf(y/r)*180.0f)/PI;
theta = (asinf(-x/(r*cosf(phi)))*180.0f)/PI;
cout<<"The radius r= "<<r;
cout<<"The phi angle= "<<phi;
cout<<"The theta angle= "<<theta;
return 0;
}
