They are not exactly the same.
In the US, the term 220V and 240V are often used inter changeably. However, for the imported electronic devices which are specifically intended to work only on 220V may be damaged from running it on 240V.
Most 220V devices will work fine on 240V. However, on some devices (mostly the ones do not have voltage regulator), it will cause over voltage for internal circuits, which lead to shortened life.

Yes, they are the same thing and used in US residential homes. If you take two 120v lines, each being 180 degrees out of phase with each other, you get 240v. Sometimes 120v lines drop as low as 110v, so the terms "110" and "220" are representing the voltage drop.
This is not to be confused with 208v, which requires three 120v wires instead of two, with each wire being 120 degrees out of phase. Typically, residential homes do not have three phase wiring, so don't purchase anything requiring 208v power unless you know for sure that it is available.

220 to 240 voltages
Yes, 220 and 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. e.g. Wattage load of 2400. Amps = watts/volts. 2400/240V = 10 amps. 2400/220V = 10.9 amps. On a constant resistance as the voltage goes lower, the current goes higher and vice versa as the voltage goes higher, the current goes lower.
Yes, a 240v heater will work with a 220v output. The slight difference in voltage should not significantly affect the heater's performance. However, it is always recommended to check the manufacturer's specifications to ensure compatibility.
In some parts of the world, an 1875 watt hair dryer can and does use 220 volts from a 220 volt outlet?
No. The black is 220, the red is 220, and the ground serves as the neutral. the last answer "no" is correct but the reason is not. the ground is still a ground. the red is 110v and the black is 110v. together they are 220v. the neutral or (common) is for a 110v return. for example a stove or a dryer will have 2 hots a common and a ground because they use 220v and 110v. 220v to power the heating elements and 110 for the controls, light bulbs or the outlet on a stove. A construction heater only uses 220v and only requires the two hots and the ground for safety.
Is the 220V plug 220V only or 110/220V? (The former will have 3 prongs and the former will have 4) If your case is the latter just use the ground, neutral, and one of the hots. This will give you 120V single phase. If the case is the former you can't get 110V off that plug.
If all the components are rated to 220V, yes. Keep in mind that if the appliance was designed for 110V it may arc if 220 is run through it. If you don't know the device can handle 220V, don't run it at 220V. Chances are it was manufactured cleaply and cannot handle the extra voltage.
It's the same thing. To make it even more confusing... your power source is 220v.
Most appliciances that are built for use with 220V would normally be fine with 240V. In most cases, they are also labeled 220-240V. Depending on how critical the application is, you should probably check with the manufacturer.
If it is a dual voltage TV, yes.
yes.
Yes, you can use a device that supports 100-240V in the Philippines as the standard voltage in the country is 220V.
Yes. As far as in the US 220v and 240v is pretty much the same thing. People call it 220 but realistically you prob have 230-240v. Get a cheap voltage tester and check it out
There should be no problem at all.
The main difference between a 220v and 240v electrical system is the voltage level. A 220v system typically refers to a split-phase system where the voltage is divided into two 110v legs, while a 240v system usually refers to a single-phase system with a higher voltage level. In practical terms, the difference is minimal and most appliances and devices can work interchangeably on both systems.
Oh yes. They do provide 2-wire 220V and even 2-Wire 240V service in Europe. We went a different way in the States early on when we attached a center-tap wire in those same service transformers to provide 2 x 110V services, along with one 220V service. It is worthy to mention that 110V (220V) services in the US progressed to 115 (230V) and now stand at 120V (240V).
Yes, a 240v heater will work with a 220v output. The slight difference in voltage should not significantly affect the heater's performance. However, it is always recommended to check the manufacturer's specifications to ensure compatibility.
Yes. Spain voltage is 220v, English is 240v (which is close enough!) Spain television uses PAL, as does English.
