The system is linear. 2. The system is non-linear. 3. The system is causal. 4. The system is non-causal. Which of the above statements is/are correct? “In any linear bilateral network, if a source of e.m.f. E in any branch produces a current I in any other branch, then same e.m.f. acting in the second branch would produce the same current / in the first branch”. The above statement is associated with
