A single strain gage has a nominal resistance of 120 ohm. For a quarter bridge with 120 ohm fixed resistors, strain gauge factor

natita [175]

Answer:

Output voltage is 1.507 mV

Solution:

As per the question:

Nominal resistance, R = $120\Omega$

Fixed resistance, R = $120\Omega$

Gauge Factor, G.F = 2.01

Supply Voltage, $V_{s} = 3\ V$

Strain, $\epsilon = 1000\times 10^{-6}\ strain$

Now,

To calculate the output voltage, $V_{o}$ :

WE know that strain is given by:

$\epsilon = \frac{(R + R')^{2}V_{o}}{RR'V_{s}\times G.F}$

Thus

$V_{o} = \frac{RR'V_{s}\epsilon \times G.F}{(R + R')^{2}}$

Now, substituting the suitable values in the above eqn:

$V_{o} = \frac{120\times 120\times 3\times 1000\times 10^{-6}\times 2.01}{(120 + 120)^{2}}$

$V_{o} = 1.507\ mV$

A heat lamp produces 32.8 watts of power at a wavelength of 6.5 μm. How many photons are emitted per second?

Svet_ta [14]

Answer:

$Photon/sec=1.07\times 10^{21}$

Explanation:

The expression for the power is:-

$Power=\frac{Energy}{Time}$

Also, $E=n\times \frac{h\times c}{\lambda}$

Where,

n is the number of photons

h is Plank's constant having value $6.626\times 10^{-34}\ Js$

c is the speed of light having value $3\times 10^8\ m/s$

$\lambda$ is the wavelength of the light

So,

$Power=\frac{n}{Time}\times \frac{h\times c}{\lambda}$

Thus, the expression for photons per second is:-

$\frac{n}{Time}=\frac{Power\times \lambda}{h\times c}$

Given that:-

Power = 32.8 Watt

$\lambda=6.5\ \mu m=6.5\times 10^{-6}\ m$

So,

$Photon/sec=\frac{32.8\times 6.5\times 10^{-6}}{6.626\times 10^{-34}\times 3\times 10^8}=1.07\times 10^{21}$
