can any body tell me what is resistance
Answers
Answer:
A force, such as friction, that operates opposite the direction of motion of a body and tends to prevent or slow down the body's motion. A measure of the degree to which a substance impedes the flow of electric current induced by a voltage. Resistance is measured in ohms.
Explanation:
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.

Answer:
the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. By Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current.
