Voltage Divider Formula

It's used for finding voltage drops across different resistance connected in series. Since in a series circuit, same current flows through each resistor, voltage drops are directly proportional to their resistance

R = R1+R2+R3

V1 = VxR1/R

V2 = VxR2/R

V3 = VxR3/R

V = V1+V2+V3
