This app simply calculate voltage divide between two series resistors and current divide between two parallel resistors.

Voltage divider :- Voltage divide in series resistors network according value of resistors. Voltage difference between two endpoints of a resistor is higher then other if value of this resistor is higher then other.

Current divider :- Current divide in parallel resistors network according value of resistors. Current divide among resistors is higher then other if value of this resistor is lower then other.
