Question

2. What will be the effect of change in the length and thickness of the electrical wire in the
experiment of electric cureent, potential differance and electric resistance?​

Answer 1

The length is directly propotional to the resistance sothe length increases resistance also increases

Answer 2

Answer:

Explanation:Thickness and length Electrical wires are made in such way that it can sustain with the respective potential difference and current flow through it. Resistance of a wire causes the flow of current. Resistance of a wire is directly proportional to its length and inversely proportional to its cross sectional area
