Question

A student obtains resistances 3; 4; 12; 16ohm using a two
metallic resistors either separately or joined together.
What is the value of resistance of each of these wires?

Answer 1

Here's your answer----------------

Let the resistance of the wires be RA and RB

Equivalent resistance when the wires are connected in series will be  RA + RB.

Equivalent resistance when the wires are connected in parallel will be

Out of the four different values of resistance's, the value of  RA + RB will be maximum.

Therefore  RA + RB is 16.

Therefore, RA  is 4 and RB is 12  .{ans}

【hope this will help ya ☺️】

Answer 2

answer is RA will be 4 and RB will be 12
4+12=16
