Characteristics of series and parallel connected resistor

Series connected resistor

1. Same current flows in every resistor connected in series
2. Voltage drop in every series connected resistor
3. Voltage drop increases with the increase in resistance and vice-versa
4. Equivalent resistance is the sum of each resistance connected in series(Req=R1+R2)

Parallel connected resistor

1. Same voltage in every resistor connected in parallel
2. Current is divided in every resistance
3. Voltage drop increases   and current decreases with the increase in resistance and vice-versa
4. Equivalent resistance is the sum of reciprocal resistance connected in parallel(1/Req=1/R1
   +1/R2)
