The larger of the two is neutral, smaller is hot.
In the US on an 120v 15a outlet it's the short slot
Looking at a duplex receptacle the right smaller slot is hot, the left larger slot is neutral and the u ground is ground.
Answer for USA, Canada and countries running a 60 Hertz supply service.Need to know the voltage of the outlet plug. On a 120 volts outlet there is one hot terminal and on a 240 volt outlet there are two hot terminals.
Not in itself. Do not plug another three prong plug in the outlet until the broken prong (round-ish) is removed from the outlet. The third prong (round-ish) on a three prong plug is the ground. It does not carry any power.Correction"It's the power return"
The long slot on a duplex receptacle is the neutral pin.
Yes, provided the outlet has a three element receptacle. The third prong is ground. If you use an adapter that connects three prongs to a two slot outlet there is a shock danger.
The smallest slot is the hot side the larger slot is the neutral slot assuming the outlet was wired correctly.
The wide slot is neutral or the return pathway for the electricty. The small slot is the hot wire. The round slot is the ground wire.

The "hot" side of the receptacle is the smaller of the two blade holes. It is on the right with the U ground facing down.
It is an outlet that has one hot wire, such as a household receptacle, or two hot wires, such as a dryer outlet (in the US). If the outlet has three hot wires, it would be called a 3-phase or polyphase outlet. These would normally be found only in an industrial setting.
In the United States, if the outlet is polarized (one slot is larger than the other), the smaller slot is the positive, or hot, assuming it is wired correctly.Another PerspectiveThe above answer is correct in that there is a "hot" and a "neutral", but technically, if you are asking about true polarity, there is no positive and no negative in a housing or commercial outlet. Utility power service is referred to as "alternating current", meaning that the true polarity of an outlet reverses 60 times per second, with one side temporarily being positive and the other negative.If you are trying to use "direct current", you will need to use some kind of diode or rectifier to change the alternating current to direct current.
