2.In the figure, current through the 3立 resistor is 0.8 ampere, lthen potential difference drop through 4立 resistor is3立3- R6立9.6 V(3) 4.8 V(2) 2.6 V(4) 1.2 V

Answer»

Current through 3 ohm = 0.8 A

Since potential drop in parallel are same.

Hence

0.8 * 3 = i * 6

i = 0.4 A

Hence current in 6 ohm resistor = 0.4 A

Now current in 4 ohm = 0.8 + 0.4 = 1.2 A

Hence potential drop across 4 ohm = 4 * 1.2 = 4.8 Volts
