series current same to all resistors p.d is divided to each resistors depending on their resistivity V = IR the resistor which have more resistance (also resistivity) gain more p.d
parallel p.d is same to all components current is divided to each resistor depending on their resistivity I = V/R more current flows through one with less resistance (also resistivity)
here as it is series connection,current is same to all resistors irrespective of their resistance
