Question

A letter 'A' is constructed of a uniform wire of resistance 3 ohm/cm .The sides of the letter are 20 cm and the cross piece in the middle is 10 cm long . What will be the resistance between the ends of the legs?​

Answer 1

Answer:

The answer will be 26.66 ohm

Explanation:

According to the problem the resistance of each wire is given

and the side length is given and the cross section is given

Now each side has the same resistance 10 x 1 = 10 ohm

Now the two sides are connected in series format

Therefore the equivalent resistance is 10 +10 = 20 ohm

Now the cross or middle portion is in parallel with the sides

Therefore the equivalent resistance is 10 x 20/10+20 = 6.66

The resistance between the ends of sides = 20 +6.66 = 26.66 ohm
