Question

4 differences between resistors in series and parallel connection

Answer 1

series  connection :
1-when two or more resistances are connected end to end continuously , they are said to be connectd in series.
2-the current remains same in the resistor.
3-the potential difference is divided.
4- here 
r=r1+r2+r3
parallel connection:
1-when two or more resistances are connected in between the same two points they are said to be connected in parallel.
2-the current is divided.
3-the potential difference remains same.
4-1/r=1/r1+1/r2+1/r3

Answer 2

Series  connection 
1) When two or more resistances are connected end to end , they are said to be connected in series.
2)The current remain constant along the circuit in the resistor.
3)The potential difference is changed after passing through  every resistor
4)R = r₁ +r₂ +........ 
For
Parallel connection
1)When two or more resistors are connected in between the same two points they are said to be connected in parallel
2)The current is changed after passing through every resistor but again comes to total at the end.
3)The potential difference remains same along the circuit.
4) 1/R= 1/r₁ + 1/r₂ ............
