Question

1. What is electrical resistance? On what does the resistance of a piece of material depend? How does resistance affect current?​

Answer 1

What is electrical resistance?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). ... Insulators: Materials that present high resistance and restrict the flow of electrons.

On what does the resistance of a piece of material depend?

Resistance depends on an object's size, shape, and material. In Figure 3 below, the cylinder's resistance is directly proportional to its length l. The longer the cylinder, the higher the resistance. Additionally, the resistance is inversely proportional to the cross sectional area A.

How does resistance affect current?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

Current is inversely proportional to the resistance. A threefold increase in the resistance would cause a threefold decrease in the current.
