the wider of the 2 blades, provided that the plug is polarized
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.
The AC wide prong is the neutral. An AC voltmeter measuring from narrow prong to ground should show line voltage; measurement from wide prong to ground should show zero. In a two-conductor power cord (and some three-conductor cords), the ridged side should be the neutral. In any light-bulb socket, the outer ridge should be wired to neutral.
The difference is safety. Any appliance or equipment that has metal parts that may be touched by the user will usually have 3 prongs because this provides for safety if those metal parts become energized. Exceptions would be "double insulated" items, such as many power tools, and items without exposed metal parts.
In a 6-30 3 prong female plug, there are two hot wires, which are usually black or red, and these connect to the two hot terminals. The neutral wire, typically white, connects to the neutral terminal, and the green wire, which is the ground wire, connects to the ground terminal.
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.

Need to know the amperage rating of the plug or the NEMA configuration of the plug and receptacle

For most standard two-prong plugs, there is no difference in which prong goes into which outlet. The prongs are typically the same size and shape, so it does not matter which way you plug it in. However, if the plug is polarized (one prong is wider than the other), make sure to plug it in the correct way according to the outlet.
The smallest slot is the hot side the larger slot is the neutral slot assuming the outlet was wired correctly.
On a 240 volt outlet, such as a dryer outlet: G is Ground, W is Neutral, X and Y are the two Hot legs.
There is an illustration at the related link below.
My question is WHY did you replace a four prong dryer plug with a three prong! 220 volt Electric dryers require two hot legs, a neutral and a system ground wire. Sounds as though you shunted one of the hots or the neutral. You need to install a four prong plug of the same configuration and wire it exactly as the original.
the round prong is the ground, the side prongs are hot and the top prong is neutral. The "Hot" Terminal screws are Brass colored. The "neutral" is silver and the "Ground" is green. Please be careful!!
