If meant ac signal then it is grounded so that the reference voltage is 0 & we get +ve voltage.
A signal generator can be used to function in two ways. In high frequencies, one of output probes of any generator (negative probe) will be grounded automatically, hence it has to be connected with grounded parts of other elements not to create a short circuit problem. But, in the case of floating type (f<100 Hz, generally) probes of the signal generator is not grounded.
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
With a common emitter amplifier it's the emitter that is usually grounded.
It is best to use both, then usually grounded, then double insulated is just OK.
Although it is common to hear the term that one is being grounded for doing something wrong, it is usually unheard of that one would be grounded for life. There was an American sitcom television show back in 2001 that was titled "Grounded for Life".
I don't really know. When I'm grounded for two weeks I usually have no phone, computer or leaving the house so I usually catch up on homework, read or workout. Good luck.
The grounded conductor is usually covered in white or light gray insulation. The grounded conductor is connected to the grounding conductor at one and only one point, usually near the transformer or in the circuit breaker panel.
Because Brian McFadden was naughty, and Shane Filan told his Dad. Then Brian's dad said "That's it, you're grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded. Go to your room. NOW!" Brian then cried to his room, only to jump out of his window, then onto a tree. Then there was Shane. Shane had a gun, then shot Brian. Brian McFadden died.
Wires may not be grounded. Trace wires to see if one has split or pulled away.
Answer is GAIN
Check all of the bulbs. If it's flashing rapidly like that it usually means that one or more of the bulbs are burned out or that one or more of the light sockets is not properly grounded.
If a circuit is grounded through a capacitor it is referred to as AC ground because ac signal can pass through the capacitor DC level is blocked
