How many electrons move past a fixed reference point every t = 2.55 ps if the current is i = 7.3 μA ? Express your answer as an

iris [78.8K]

Answer:

116.3 electrons

Explanation:

Data provided in the question:

Time, t = 2.55 ps = 2.55 × 10⁻¹² s

Current, i = 7.3 μA = 7.3 × 10⁻⁶ A

Now,

we know,

Charge, Q = it

thus,

Q = (7.3 × 10⁻⁶) × (2.55 × 10⁻¹²)

Q = 18.615 × 10⁻¹⁸ C

Also,

We know

Charge of 1 electron, q = 1.6 × 10⁻¹⁹ C

Therefore,

Number of electrons past a fixed point = Q ÷ q

= [ 18.615 × 10⁻¹⁸ ] ÷ [ 1.6 × 10⁻¹⁹ ]

= 116.3 electrons

Advance (also called Constantan) has a strain sensitivity SA=2.1 for strain as large as 8%. Determine the amount of contribution

Sholpan [36]

Answer:

$\frac{dP}{P} = 6.25$

Explanation:

Given data:

Sa = 2.1

$R = \frac{pl}{A}$

$\frac{dR}{R} =\frac{dP}{P} +\frac{dL}{L} (1_2V)$

$\frac{dR}{R} =\frac{dP}{P} +\epsilon (1_2V)$

$Sa = \frac{\frac{dR}{R}}{\epsilon} =\frac{\frac{dP}{P}}{\epsilon} +\frac{\epsilon (1_2V)}{\epsilon}$

$Sa = (1+2v) + \frac{\frac{dP}{P}}{\epsilon}$

change in specific resistance is given as $\frac{dP}{P}$

$\frac{dP}{P} = \frac{Sa -(1-2v)}{\epsilon}$ ........2

where v is elastic range = 0.30

$\epsilon = 0.08$

$\frac{dP}{P} = \frac{2.1 -(1-2\times 0.30)}{0.08}$

$\frac{dP}{P} = 6.25$
