ELI5, what is electrical resistance?
In: Physics
You want to fill a bucket with water from a large water deposit. Now imagine these 3 options :
– you just open the tap and let the water flow free from the water deposit. The bucket fills quickly.
– you open the tap but attach a pipe full of cobblestones . The water flows but slower, since it has to go around all the little stones inside the pipe, taking more time to fill the bucket.
– now you fill the pipe with sand, or cotton. The bucket will eventually fill too, but taking a long time.
This opposition that the water finds to flow thru a pipe is pretty much like electrical resistance for electric charges.
