That is a grounding pin. It provides a easy path for electricity to go to ground (all electricity seeks "ground" and will take the easiest path) By having the grounding pin it there it will hopefully prevent the easiest path to ground from being through YOU. Which would cause you you to get shocked.
The third prong connects the body of the appliance directly to ground.
On a British plug it is the earth pin connected to the earth wire. This is safety feature to stop electric shock
An appliance with a three-prong plug is designed to be grounded for safety. Plugging it into a two-slot socket on an extension cord eliminates the ground connection, increasing the risk of electrical shock or fire in case of a fault. It is important to always use a proper outlet or extension cord that matches the appliance's plug for safety reasons.
The third derivative of the function x with respect to time is the rate of change of the acceleration of x with respect to time. It is denoted as d3x/dt3.
To test a 2 prong sealed beam light, first disconnect the light from the power source. Then, using a multimeter, set it to the continuity test mode. Touch one lead of the multimeter to one prong and the other lead to the second prong. If the multimeter beeps, it indicates that there is good continuity and the sealed beam light is functioning properly.
The rate of change of the quantity represented by the function d3x/dt3 is the third derivative of x with respect to t.
The 3rd round plug is the ground connection.
The third prong on the bottom of the plug is for "grounding," in case of a short.
If the third prong on your plug breaks off, you should stop using the plug immediately and replace it with a new one to ensure safety and proper functioning of your electrical devices.

The reason might be a voltage or amperage mismatch between the two devices. Plugs and receptacles are matched sets depending on the voltage and the amperage of the devices. The configurations are done in this manor to prevent the wrong voltages being applied to wrong plug in equipment.
No you can not you will need to replace the plug with a 4 prong the same as the style of your oven and change your breaker to the correct Amp for your style of 4 prong plug
Ground wire
Yes, there are stove plug adapters available that can convert a 4-prong outlet to a 3-prong outlet.
I don't know about an extension cord, but they do sell plug adabters. You can pick them up at any hardware store or even Wal-Mart. They are ussaully grey or orange , and look like the plug end of the extension cord. One end will have the 2 prong, the other side will have the slots to plug in the three prong.
Need to know the amperage rating of the plug or the NEMA configuration of the plug and receptacle
No, the wide prong is neutral it is the white wire. The narrow prong is hot it is the black wire. The round prong (in a 3 wire plug) is safety ground it is the green wire.
US dryers commonly use a 3-prong or 4-prong plug. The 3-prong plug has two flat blades (hot) and a L-shaped prong (neutral), while the 4-prong plug has two flat blades (hot), a round prong (neutral), and a half-round prong (ground). It's important to match the plug with the corresponding outlet for safety and proper functionality.
