i have some questions.
1. Given two pieces of copper wire which have same length but different diameters and based on equation R=ρ(L/A),determine the relative resistance of a piece of wire provided that its diameter is twice as long as that of the other one.
2. Given a resistor with bands 1=blue,2=orange,3=green,4=silver;find the resistance value and tolerance.
3. Comparing the measured 6.522kΩ with the calculated one , state the error percentage
and verify whether the Ohm's Law is correct.
