Question

triangle made of wire of resistance 24 ohm side of triangle is ab 3 cm bc 4 cm and ac 5 cm find resistance of side ab

​

Answer 1

Answer:

6 ohm

Explanation:

in these case all the resistance is in series combination.

3X+4X+5X=24

12X=24

X=2

so resistance in AB=3×2=6ohm

Answer 2

Concept Introduction:

Ohm's law states that the electric current is directly proportional to voltage but inversely proportional to resistance. A refusal to give in or to something that slows down or prevents something is known as resistance. Resistance is measured in ohms.

Given:

We have been given,

Triangle made of wire of resistance 24 ohm

AB= 3 cm, BC= 4 cm and AC=5 cm.

To Find:

We have to find the resistance of side AB.

Solution:

According to the problem,

Let, the resistance of each side is x.

3x+4x+5x=24

12x=24

x=2

So, resistance in AB= 3×2= 6

Final Answer:

The resistance of side AB is 6 ohm.
