. In circuit A, two resistors R1 and R2 are connected in series. In circuit B, two identical resistors are connected in parallel. Both circuits are powered by identical energy sources and include no other resistors. In which circuit, if any, is the current greater across R1?
Homework Answers
We know ,current=i=voltage /Resistance.
So when resistor are in series the voltage get divided of total power supply between R1 and R2 But when R1 and R2 are in parallel both get same voltage as of power supply.
It means when resistor are in parallel voltage across R1 is more as compare when it is in series .Therefore when R1 in parallel it will get more Current.
