Introducing Ohm and Kirchhoff

Today, I learned about Ohm's Law in Physics class. Mylifeisaverage
ooOOOoooOoo I feel like a scientist,
but all my discoveries are from the internet.

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them.[1]
The mathematical equation that describes this relationship is:[2]
I = \frac{V}{R}
where I is the current through the conductor in units of amperesV is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.

Kirchoff;

Series Circuit(Series Circuit)
The total voltage is the sum of the voltage on each component.
eq 1: V0 = V1+ V2 + V+...+ Vn(In this case, VT = V1+ V2)
The total resistance is equal to the sum of the resistance on each component.
eq 2: R0 = R1 + R2 + R3 +...+ Rn(In this case, RT = R1 + R2)
The total current is equal in every component.
eq 3: I0 = I1 = I2= I3= I4 =...= In(In this case, IT = I1 = I2)

The total voltage is equal in every component.
eq 4: V= V1= V2= V=...= Vn(In this case, VT = V1= V2)The resistance is equal to the sum of resistance on each component divided by the product of resistance of each component.
eq 5: 1/R0 = 1/R1 + 1/R+...+ 1/Rn(In this case, 1/RT = 1/R1 + 1/R2)
The total current is equal to the sum of current in each component.
eq 6: I0= I1 + I2 + I3 + I4 +...+ In(In this case, IT = I1 + I2)



i like haikus;

Does MENSA accept
pseudo-scientists, who blog
about real science///
