Find the unknown value r3
WebR 1 / R 2 = R 3 / R 4. From the above equation, we can calculate the value of the unknown resistance value. As the galvanometer can be used to reach the balanced point very precisely, and if the values of the known resistances are known to a high precision as well, the value of the unknown resistance, in the above case R 4, can be calculated very … WebApr 9, 2024 · Kirchhoff’s second Law/ KVL. Kirchhoff’s second law concept is also very useful for circuit analysis. In his Second law, it is stated that “For a closed loop series network or path, the algebraic sum of the products of resistances of the conductors and the current in them, is equal to zero or the total EMF available in that loop”. The directed sum …
