Why would you not connect a three prong plug to a two hole cord? The casing of a three prong electrical device attached to a two prong socket is not grounded. If a high power device is attached to a two prong circuit, and there is a short to the casing, the person holding the device could get a nasty shock.

Why can’t i Plug an extension cord with 3 prongs?
If an extension cord’s socket has just two slots, you have no way of forcing a plug with 3 prongs into those slots. The third prong will get in the way.
Can you plug a 3 prong plug into a 2 prong outlet?
For maximum protection, you must plug a 3-prong plug into a 3-prong outlet. This is why people are cautioned against fitting a three-prong plug into a two-prong outlet by removing the plug’s third prong. While it is convenient, the habit elevates the risk of electrocution.
Are two-prong plugs safer than three-prong plugs?
Is one version safer than the other? Two-prong plugs are just as safe as three-prong plugs, Tom. All tools, whether grounded or double insulated, carry a first layer of protection: the rubbery insulation coating on the wires and other components inside the tool.
What happens if you don’t have a third grounding plug?
This powers the appliance. In the absence of a third grounding plug, if a malfunction occurs, the electricity will follow the path of least resistance, which is normally the metal casings and components of appliances and gadgets. As you may have guessed, this can lead to the consumer’s electrocution.
Is it safe to plug a 3 prong plug into a 2 prong outlet?

Touching even a single exposed strand can give you an electric shock or burn. Never use three-prong plugs with outlets that only have two slots for the plug. Do not cut off the ground pin to force a fit. This defeats the purpose of a three-prong plug and could lead to an electrical shock.
How do you wire a 2 wire plug to a 3 wire?
How to Replace Two-Prong Outlets to Three:Step 1: Check for ground. ... Step 2: Remove the old receptacle. ... Step 3: Connect the new receptacle. ... Step 4: Fasten the ground screw. ... Step 5: Ground the receptacle. ... Step 6: Turn on the power.
What is the difference between 2-prong and 3-prong outlets?
The main difference between a two-prong outlet and a three-prong outlet is that a three-prong outlet has a ground wire, while a two-prong outlet doesn't.
What is a 3 to 2 prong adapter?
A cheater plug, AC ground lifter or three-prong to two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots). The use of such an adapter avoids the need to replace receptacles.
Why do 2 prong plugs have holes?
These bumps fit into the holes so that the outlet can grip the plug's prongs more firmly. This detenting prevents the plug from slipping out of the socket due to the weight of the plug and cord. It also improves the contact between the plug and the outlet.
Are 2 prong plugs safe?
This is what makes two-prong outlets the least safe of any type of outlet. Two-prong outlets have connections only for hot and neutral wire, hence their name. Without a third-prong for a connected ground wire, unstable electricity doesn't have a path to travel safely away from you and your electrical system.
2-Prong Plug In 3-Prong Extension Cord: Is It Possible?
I see that you’ve decided to read the article. So, you really want to find out whether you can put a 2-prong plunge in a 3-prong extension cord.
The Physics Behind 2-Prong And 3-Prong: Explained

That was my take on whether you can use a 2-prong plug in a 3-prong extension cord. I hope that I have been able to answer your questions.
Why not use a grounded plug adapter?
Another reason to not use a grounded plug adapter is the appliance’s possibly unsafe condition. One tragic example was in 2005 when Tarun Mal, an associate professor at Cleveland State University, was electrocuted when he plugged a defective fluorescent lamp into a time switch using a grounded plug adapter.
What happens if you plug in a grounded plug?

What would have happened if Mal had used a ground fault circuit interrupter?
If Mal would have used a ground-fault circuit-interrupter instead of a grounded plug adapter, he would have been safe. The circuit interrupter automatically cuts electrical power to an appliance when it senses that the electrical current flowing through the outlet or device has found an unintended route. (Do note, though, not all GFCI outlets ...
