Question

in a circuit a wire of certain length and thickness was used and reading of ammeter was noted now it is replaced by a thick wire of same material and same length in same circuit the reading of ammeter will​

Answer 1

Answer

• If the thin wire is replaced by a thick one of the same material and of the same length then the ammeter reading will Increase

━━━━━━━━━━━━━━━━━━

• As the Thickness of the conductor increase the current also increases $\sf .$

• This can be understood with the example of two water bottles, one with a narrow opening and one with a wider opening (Opening of the bottles represents the thickness of the wire).

• If you fill both the water bottles with equal amounts of water (Here water represents current) and then tilt both these bottles upside down we'll observe that the bottle with a wider mouth emptied faster than the one with a shorter opening.

• This was because as the opening was larger the water molecules that could flow through was also more.

• Connecting this to the concept of electricity we see that as the thickness (opening) of the electrons (water) that could flow through increase and hence more current flows in the same same time

Answer 2

$\huge\underline{\bf{Answer}}$

⠀⠀❍ Reading of ammeter will increase.

⠀

$\huge\underline{\bf{Explanation}}$

⠀

★ Given :-

• Firstly, it is given that a wire is used in a circuit with a certain length and thickness.

⠀

★ Changes :-

• The wire is replaced by another thick wire of same material and same length in that circuit.

⠀

★ Causes :-

• When we increased the width of wire, then the current through the wire also increases.

⠀

★ Conclusion :-

• In result of increase in width of the wire i.e., current through the wire increases the rate of current that is recorded in the ammeter.
