What is the equivalent resistance of a circuit that contains four 75.0 resistors connected in series to a 100.0 v battery

solong [7]

The equivalent resistance of several resistors connected in series is
the sum of their individual values.

Four 75-ohm resistors connected in series are electrically equivalent
to a single resistor of 300 ohms.

The battery voltage doesn't matter. In fact, it doesn't matter whether the
resistors are anywhere near a battery or not. They could just as well still
be in the little Radio Shack envelope on the top shelf of the storage room.
If they're connected in series, then they're still electrically equivalent to a
single 300-ohm resistor.

Consider a product with three components in series, with reliabilities of 0.90, 0.80, and 0.99 for components A, B, and C, r

Feliz [49]

Answer:0.853

Explanation:

Given

Reliability of A is 0.90

Reliability of B is 0.80

Reliability of C is 0.99

B has a backup with reliability of 0.8

i.e. B has a component in parallel to it.

A,B& C is series.

B actual reliability is

$R_b=1-\left ( 1-0.8\right )\left ( 1-0.8\right )$

$R_b=0.96$

Thus $R_{net}$ is given by

$R_{net}=R_A\times R_B\times R_C$

$R_{net}=0.9\times 0.96\times 0.99$

$R_{net}=0.8553$

What is Stefan Boltzmann's law??? Need explaination

sukhopar [10]

Answer:

The Stefan–Boltzmann law, also known as Stefan's law, states that the total energy radiated per unit surface area of a black body in unit time (known variously as the black-body irradiance, energy flux density, radiant flux, or the emissive power), j*, is directly proportional to the fourth power of the black body's
