Two resistances 3ohm and 6ohm are connected in parallel and the combination is connected to a series with a resistance 2 ohm and a cell of emf 2v and internal resistance 1ohm find 1.Current through the cell 2.current through 3 ohm resistor 3.current through 6 ohm resistor 4.Pd across 2ohm resistor Lost volt within the cell |
We have, R1 = 3ohm ,R2=6ohm ,R3 =2ohm V=2V,r=1ohm Effective resistance=4 ohm Current through the cell=2/5=0.4A Current through 3ohm resistor=2/3=0.66A Current throug 6ohm resistor=2/6=0.33A P.d across the 2ohm resistor=0.4*2=0.8V |
