A spike demonstrated in that picture is so tiny as to be called noise. All electronics already contain protection that makes that irrelevant. And that makes most surges irrelevant.
The concern is another type of surge (caused by lightning or a stray car) that can overwhelm protection already inside appliances. Protector adjacent to a TV does not claim to protect from that type of surge. Another and completely different device (also called a surge protector) to protect from typically destructive surges is located at the service entrance (ie in a breaker box or behind the meter). This makes an essential, short connection to earth ground electrodes. Then a surge current is not inside the house hunting for earth destructively via a TV or any other appliance.
You can plug your TV into a surge protector. But that protector also needs protection by another protector that makes the short connection to earth.

∙ 12y agoThe circuitry inside is passive. It consists of capactitors and inductors, to remove radio and mains bourne interference. Anything can be plugged in, if it benefits from anti surge, all well and good. If it doesn't, (like a toaster) then no harm done.

What happens when you plug a GFCI protected extension cord into an outlet that is GFCI protected?
In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)
What device senses short circuits and stops electrical flow when ground fault occur?
It is a Ground Fault Circuit Interrupter or GFCI. It can either be equipped in your electric panel as a GFCI breaker, or in a GFCI outlet which also lets you extend the GFCI protection to other outlets "down the line" from the GFCI outlet.
Where does a GFCI go?
GFCI protection is required for most outdoor receptacles, bathroom , garage wall outlets, kitchen, and all receptacles in crawl space.
Why won't the GFCI trip the panel box when shorted?
A GFCI is not an overcurrent protection device. It only protects people from electrical shock. However, if you were to create a perfect hot to neutral short the GFCI would not trip and the panel breaker would.
Do dishwashers require GFCI protection?
Is the outlet located near a water source, if so, yes.
Can you use a GFCI plug into a GFCI outlet?
Yes you can. Lots of blow dryers have GFCI protection built in.

Why and when would you use a GFCI breaker within a older home with a groun?
You need a GFCI outlet at any location that is within 6' of a water source. You also need a GFCI outlet in a room with a concrete floor, any garage, and any location outside the home or under the home in the crawl space. A GFCI outlet protects you from electrical shock near water or moisture. You can protect more than one outlet with 1 GFCI outlet. Connect the incoming power to the LINE side of the GFCI outlet and all the other outlets getting power from that outlet to the LOAD side of the GFCI outlet. That way they will all be protected by 1 GFCI. A GFCI breaker is used to protect an entire circuit and not just individual receptacles. It is often cheaper to use GFCI receptacles than a breaker, especially if "piggy-backed" such as described above. It is also more convenient to reset a GFCI receptacle than to reset a breaker. But your question is "why." From this I suspect you may be misunderstanding the difference between a breaker and GFCI protection. To keep things simple let me say that a GFCI does not work on the same principles as a standard breaker. It provides a much safer protection than a standard breaker. Even with a ground you need GFCI protection as listed above.

Can a circuit with a GFCI be shared at the box?
Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
Why won't the GFCI trip the panel box when shorted?
A GFCI is not an overcurrent protection device. It only protects people from electrical shock. However, if you were to create a perfect hot to neutral short the GFCI would not trip and the panel breaker would.
Is it NEC code to have a water fountain on a GFCI protection?
Yes. NEC 2005 440.21
Do dishwashers require GFCI protection?
Is the outlet located near a water source, if so, yes.
Do you wire a gfci outlet differently?
No, except that you insert the wires into the holes on the back of the outlet. The power in connects to the LINE side of the outlet and power out connects to the LOAD side of the outlet. This is clearly marked on the back of the outlet. This will not only protect the outlet with the GFCI installed but all outlets receiving their power from that GFCI. If you do not want to protect the outlets receiving power from the outlet then connect that outgoing wire to the LINE side also. But know that only the outlet with the GFCI will be protected and all other outlets will not be GFCI protected.
What happens if you trip a GFCI repeatedly on purpose?
Every time you trip the GFCI, the power to the device plugged into it will lose its supply voltage.
When would it be a better idea in a residence to install a GFCI breaker instead of an GFCI outlet?
GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.
