HEP CB: VOLTAGE DIVIDER DERIVATION (Vout)

 Resistor - two‑terminal electronic component that provides electrical resistance measured in ohms. Heres some of the core topic of the function based component.

VOLTAGE DIVIDER DERIVATION

Sum of voltage = zero

+Vin - I1 (R1) - I2 (R2) = 0

Vtotal = I(R1+R2)

nothing follows...

Another:

Itotal = I1 [resistor one]+ I2 [resistor two]

Since I1 = I2 = Itotal

and by ohms law:

 Itotal = I2

Vin/(R1 +R2) = Vout/R2

since Vout is needed...

Vout = Vin (R2)/(R1 +R2)

THATS IT! ENJOY!
