circuit diagrams......

Q2. 2A all the resistances except the 6ohm (outside the combinatition) one are shorted hence no current will pass thru them hence net resistance = 6 ohm and hence current = V/R = 12/6 = 2A

som1 pls solve 1&3......urgent.............................

can u tell meh d dirction of currnt #3A in d first loop

for 3
i think its 1:1
becoz its wheatsone bridge....

thanxx .....
