"Stronger" isn't a good word here.
Given the most common D and 9V batteries, it's more a question of "different" than "stronger".
The 9V has a higher voltage, while the D cell has a bigger capacity. What'll be best depends on what you need. It's like trying to decide if a sports car is better than a tractor.
A 9 volt battery is stronger than a 1.5 volt battery because it has a higher voltage. The higher voltage allows the 9 volt battery to power more demanding devices and last longer than a 1.5 volt battery.
no
you better not. you need a 9V regulator for this, not a resistor!
You can buy 9V batteries from almost any supermarket
no
No.
Yes, a 9v battery can be dangerous if mishandled or ingested, as it can cause burns or internal injuries. Ingesting a 9v battery can also lead to serious health complications or even death. It is important to handle and store batteries properly to avoid accidents.
A car battery has six cells each producing two volts. A 9v alkaline battery has six cells each producing 1.5 volts. There are some obvious differences, like that a car battery can put out hundreds of amps and a 9v alkaline can only put out hundreds of milliamps, a 9v battery weighs 45 grams versus 45 pounds for a car battery, and so on.

yes the invert mini takes 1 9v battery. it is in the grip frame. you should get a 9v with the gun/
Current I = V/R V = 9V R = 100ohm I = 9V/100ohm = 90mA
No.
