Does a resistor have polarity Why or why not?
No the resistors are bidirectional and can therefore be used in both directions.
Do not go wrong with the colored lines, it’s just to say the approximate resistance.
The resistors are purely passive components and have a linear response when the voltage is applied to one or the other polarity.
A resistance shows no polarity bias. Why? because it’s characteristic of the electric current. it’s like why things fall to the ground once released. because of gravity. Why? because it is the nature of gravity to attract things that are released.
No, they can be placed anyway because the resistors have no polarity, so they work well in both directions, but you want your circuit to be readable, so it’s good practice to choose a direction and to follow her to be able to Read your tapes without having to return the thing in the hand or in the head.
No, they have no polarity in the sense that they behave the same way when they are reversed.
It is because they rely on the overall resistivity of the materials to obtain their characteristic resistance. and this resistivity has no sign and it has no electrical properties that differentiate it in one direction or the other.
In some circuits, the design of the resistors modifies the function of the circuit according to their direction. the wound resistors for example.
In actual design work, most of the time, I consider the resistors as if they were polarized / omnidirectional, so I have a simpler task to do later to make the layout of the board or lower the time placement in the machine to pick and deposit.
To do this, I always mark pin 1 in the diagrams and later in the printed circuit board.
If I understand your question, then yes – the resistors are reversible, in the sense that they can be connected to the circuit in both directions. the resistors do not look like diodes or capacitors.
They have no polarity. the conductive current (or resistor) also in both directions of flow of the current.
In manufacturing, you will often see resistors installed in the same direction. Two main reasons for this are that  component placement and insertion equipment generally install resistors in the same orientation because it is simpler, and  the resistors are all oriented in the same way facilitates inspection and troubleshooting.
Nope. stick to it as you please. I usually put the insulated tape to the left if they are horizontal and down if they are vertical (compared to the bottom of the board), as this makes viewing easier when I’m reviewing a circuit. No matter how they go, they will work the same way.
The diodes are polarized. do not stick them in the wrong way. things just do not work if you do it. some capacitors are too. do not stick a cap in the wrong direction.
You’ll just have a shot, then you’ll have to swear a bit and do some desoldering and a little more soldering by sticking a new po but no resistances. they are content to draw in both directions. that’s how they are made.
The resistance comes either from the materials of the body or winding. no matter the meaning of the juice, the resistance remains the same.
