In a Wheatstone bridge, if the resistances are P = 10 Ω, Q = 20 Ω, R = 30 Ω, and the bridge is balanced, what is the value of S?

Three resistances P, Q, R each of $2\Omega$ and an unknown resistance $S$ from the four arms of a Wheatstone bridge circuit. When a resistance of $6\Omega$ is connected in parallel to $S$ the bridge gets balanced. What is the value of $S$

Kirchhoff's Loop Rule is based on the conservation of which quantity?

Which of the following is NOT a correct statement about Kirchhoff's laws?

$A,\,\,B,\,C$ and $D$ are four resistances of $2\,\,{\rm{\Omega }},\,\,2\,\,{\rm{\Omega }},\,\,2\,\,{\rm{\Omega }}\,\,{\rm{and}}\,\,3\,\,{\rm{\Omega }}$ respectively. They are used to form a Wheatstone bridge. The resistance $D$ is short circuted with a resistances ${\rm{R}}$ in order to get the bridge balanced. The value of $R$ will be
