If the voltage of your circuit is 36 volts and the current is 9 amps what is the resistance?

Aswer:

To find the resistance of a circuit, Ohm's law is used:

Taking as data:

Volts(v) = 36

Current(I) = 9 amps

Resistance(r) = ¿?

We replace according to the formula:

v/i = r

Result: The resistance of the circuit is 4 Ohms.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
