The length of the material can be measured with a ruler or caliper, and its resistance with an ohmmeter. Knowing these values, it is possible to calculate the resistivity of the material ? on:

?= R A/L

(a) What will happen to the material’s resistivity if the resistance is increased?

(b) What will happen to the material’s resistivity if the length is increased?

?= R A/L

(b) What will happen to the material’s resistivity if the length is increased?

You can still ask an expert for help

Given,

$\rho =\frac{RA}{L}$

a) if R is increased, there will be no effect on Resistivity because Resistivity is the property of material and it only depend on material.

b) if L is increased, then also Resistivity will not change.

I was looking at the data sheet for a copper cable and noticed the conductor resistance to be specified at around 5 mOhm/m. This is magnitudes higher than pure copper, which has a resistance in the order of 10 nOhm*m. Why is the resistivity so much higher?

Prove or Disprove that $\left|\frac{{e}^{2i\theta}-2{e}^{i\theta}-1}{{e}^{2i\theta}+2{e}^{i\theta}-1}\right|=1$

This is a step in an attempt to solve a much larger problem, thus I'm fairly sure it's true but not absolutely sure. It looks like it should be simple but it's resisted all my attempts so far.

A capacitor is charged to a potential of 12.0 V and is then connected to a voltmeter having an internal resistance of $3.40M\mathrm{\Omega}$. After a time of 4.00 s the voltmeter reads 3.0 V.

What are (a) the capacitance and (b) the time constant of the circuit?

This is kind of a stupid question and I am taking some risk of getting some down-votes here, but, I can't resist posting it. Suppose $({u}_{1},{u}_{2})$ is an orthonormal basis for ${R}^{2}$, and let x be an arbitrary vector in ${R}^{2}$, then we can decompose x by projecting on ${u}_{1},{u}_{2}$, i.e.

$\begin{array}{r}({u}_{1}^{T}x){u}_{1}\\ ({u}_{2}^{T}x){u}_{2}\end{array}$

Certainly we have

$\begin{array}{r}x=({u}_{1}^{T}x){u}_{1}+({u}_{2}^{T}x){u}_{2}\end{array}$

Looks like a simple problem, but how can I prove this?

$\begin{array}{r}({u}_{1}^{T}x){u}_{1}\\ ({u}_{2}^{T}x){u}_{2}\end{array}$

The current is maximum through those segments of a circuit that offer the least resistance. But how do electrons know beforehand that which path will resist their drift the least?
