what is the resistance of connecting wire,ammeter and voltmeter

resistance of connecting wire depends on many factors like the material taken(which is copper usually), the length of the wire and area of cross section of the wire.
if you know the length(l), area of cross section(A), and resistivity of the material(rho-ρ)
then you can calculate it by ρ×l÷A.
Coming to resistivity of ammeter, it is very very low, and that of voltmeter is very very high.
Hope this was helpful.
GOOD LUCK.

Answer: Usually negligible wires will have a listed ohms per unit length , which is usually so small that it can be safely ignored, or included as the par of the resistance of the non ideal Voltage source.
Explanation: it depends on the factors like length of the conductor , area of the cross section , temperature, material strength .
I think it is helpful to you.
Give me good response.
Thankyou
