1.	Two square metal plates A and B are of the same thickness and material. The side of B is twice of that of A. These are connected as shown in figure (series connection). If RA and RB are the resistances of A and B, respectively, then RA/RB is
Answer» Two square metal plates $A$ and $B$ are of the same thickness and material. The side of $B$ is twice of that of $A$ . These are connected as shown in figure (series connection). If $R_{A}$ and $R_{B}$ are the resistances of $A$ and $B,$ respectively, then $R_{A} / R_{B}$ is
