r u sure???

In order to find the voltages accros the parallel resistors. u have to subtbract the voltage being used up in the series and the voltage is then given to teh 2 parallel resistors
well what if the resistance of the series resistor is higher than total resistance of parallel ristors?
does the current flow thro the parallel first then?

ok suppose V = 10V
Series Resistor = 3ohms
Each parallel Resistor = 2ohms
thus, combined parallel resistance = 1 ohm.
so the parallel resistors get , 1/4*10 = 2.5Volts and the series resistor gets = 7.5Volts

a steel bar is hanged near an electromagnet....
A ( attract attract )
B ( attract repel )
C ( repel attract )
D ( repel repel )
