Which situation will have the highest resistance?
A. long wire and high temperature
B. short wire and high temperature
C. long wire and cold temperature
D. short wire and low temperature

Option C. Long wire and high temperature will have the highest temperature.

Explanation:

The resistance is used to determine the position at which the circuit is.

Resistance and current are inversely proportional.

The electrons in the wire moves and gets collide with the ions in their travel. Due to this collision the current decreases and resistance rises.

Therefore the long the wire is the higher the resistance will be.

Resistance rises with temperature, because the electrons pick up energy with heat, move around more vigorously, and as discussed above during the electron collision the more they collides the more heat is released.

Therefore the long wire and high temperature will have the highest temperature.

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

it doesn't. it was imagined up in the middle ages.
