Question

In the circuit shown in the figure, find the magnitude of current through 3 resistance. In A. 1 significant figure 20 TH +6V + 60 +3V tilt

Answer 1

The above problem can be solved using application of KCL in the above circuit. Please refer to the below image  for detailed explanation:

Solution 8- Giren circuit :- +3v 22 wile +6r Iz (ه) va +3v Is elit Holo =%. Applying KCL in the above circuit at node a' node 'b' as refference we get or node and considering that :- = > Va -34 Vate + Va-3 2 3 6 3(va-3) + 2Va +12 +(Va-3) =0 6 3ra-9 + 2 vat12 tva-3 = 0 Gva-12 +12=0 => Va=0 volts =) => 0 ". Current through 32 resistance is given by :- Vat6 as va 2) o+6 Amps {as 3 o volts 3 => I2 = 6 = 3 응 2 Amps Answer
