1.

if in the given arrangement the three resistors are to be replaced by a single resistor. what will be the value of this resisitors ?​

Answer»

Explanation:

If resistances is converted into single RESISTOR, it is CALLED as

EQUIVALENT Resistance.

So the equivalent resistance in this case will be

1st

We can SEE that 6 ohm and 6 ohm are in parallel.

So, 1/6+1/6=1/3

So, the parallel resistance is 3 ohm.

2nd

Now, we can see that 3 ohm and 6 ohm are in series.

So,

3 ohm+ 6ohm = 9 ohm.

Answer is 9 ohm as Equivalent Resistance.
