Answer:

The total resistance is 15 Ω, the total current is 1A, The potential drop in R1 and R2 are 10V and 5V respectively and the total power develped is 15 W.

Explanation:

First it is necessary to simplify the circuit. We can do this by calculating the total or equivalent resistance Re. For series resistance arrangement, Re is computed as:

RT = R1 + R2 = 5 Ω + 10 Ω = 15 Ω

According to Ohm’s law the total current can be calculated dividing the total voltage V by Re:

I = V/Re = 15V/15Ω = 1A  

This current will be the same current through R1 and R2. Then we can compute the potential drop across R2 multiplying the current across R1 by the resistance:

VR1 = I*R2 = 1 A * 10 Ω = 10 V  

The potential drop across R2 is obtained in the same way as R1, considering R2 resistance:

VR2 = I*R1 = 1 A * 5Ω = 5 V

The total power could be calculated multiplying the total current I by the total voltage:

P = I*V = 1 A * 15 V = 15 W

How do you change matter into other phases of matter?
Vera_Pavlovna [14]
Hey there!

There's many ways to do it - like melting and evaporating.

For example, we'll use water. Plain old water in a water bottle. Right now, it's in its liquid state of matter, but say you put it in the freezer for an hour. That would change its state of matter to solid, since it would be solid ice. Now, if you were to put it out in the sun on a blazing hot day for a couple of hours, it would evaporate and become water vapor, a gas. Lastly, if you can cool that water vapor it becomes a liquid again.

Hope this helps!
