In the given circuit the value of I 1 + I 3 I 2 is:

Correct answer

0

Step-by-step solution

Potential distribution at each point in the circuit is shown in above diagram. Since, both 10   Ω resistors are maintained at same potential difference, so current will be same, thus, using Ohm's law, I 1 = I 2 = 20 - 10 10 = 1   A Now, current I 3 = 10 10 = 1   A Hence, the value of I 1 + I 3 I 2 = 1 + 1 1 = 2 .
