If a 4 Ω resistor, a 7 Ω resistor, and a 12 Ω resistor are connected in a series, which resistor has the most current in it?
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
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
