Q-2 What are free electrons ?
Answers
Answer:
1.Ohm's law show the relationship between potential difference and current, where as it states that potential difference is directly propotional to current. mathematical expression for ohm's law is. V α I. i.e., V=IR.
2.any electron that is not attached to an ion, atom, or molecule and is free to move under the influence of an applied electric or magnetic field.

Ohm’s Law Definition
•───────────────────•
Most basic components of electricity are voltage, current, and resistance. Ohm’s law shows a simple relation between these three quantities. Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Ohm’s Law Formula
•───────────────────•
Voltage= Current× Resistance
V= I×R
V= voltage, I= current and R= resistance
The SI unit of resistance is ohms and is denoted by Ω
This law is one of the most basic laws of electricity. It helps to calculate the power, efficiency, current, voltage, and resistance of an element of an electrical circuit.
