Question

answer the question no 4

Answer 1

total resistance 10 ohm+2ohm =12 ohm
v=12
i=v/r=1 ampere
current in 10 ohm R is 1 A
voltage =iR=10 volt
R across 3 ohm and 6 ohm Resistance will be 2 ohm
thus in parallel combination current devide so current in 3 ohm resistance will be=V/R
=2/3
=0.66..
=0.67A

Answer 2

Hi friend,
first of all, we will find the effective resistance the of circuit
effective resistance of circuit is 10 ohm + 2 ohm(parallel circuit)
effective resistance is 12 ohm
Now by using ohms law
V = IR
12 = i * 12
12 / 12 = 1 ampere
Hence current flowing throughout the circuit is 1 ampere
Current flowing in resistor = resistance of resistor * current flowing throughout the circuit
Therefore current flowing in 10 ohms resistor is 10 ohm
current flowing through 3 ohm is 2 / 3= 0.66....
current flowing through 6 ohm is 2 / 6 =0.33...

Hope this helps
