Along the direction of current across a resistance, the potential drops. From positive terminal of a battery to the negative terminal of a battery, potential drops and vice-versa. For loop abcdefga, gain in potential has been taken as positive and drop in potential has been taken as negative.

Q. Mark the correct equation:

For loop ahdba; $30 i_{1} + 45 - 41 i_{3} = 0$

For loop ahdefga; $- 30 i - 21 i_{2} + 80 = 0$

For loop abcdha; $41 i_{3} - 45 + 30 i_{2} - 80 = 0$

For loop abcdefga; $41 i_{3} - 45 + 21 i_{2} - 80 = 0$

Q. Mark the correct equation:

For loop ahdba; 30i1​+45−41i3​=0

For loop ahdefga; −30i−21i2​+80=0

For loop abcdha; 41i3​−45+30i2​−80=0

For loop abcdefga; 41i3​−45+21i2​−80=0
