1. What is electrical resistance? On what does the resistance of a piece of material depend? How does resistance affect current?
Answers
Answer:
Electrical resistance is a object which resist the flow of electric current. It is proportional to the length of the wire. It is inversely proportional to the area of wire. Resistance resist the flow of

Answer:
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). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
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 relationship between resistance and the area of the cross section of a wire is inversely proportional . When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result.
