Question

the maximum resistance which can be made using four resistors each od 1/2 ohm is​

Answer 1

Thus the value of maximum resistance is 2 ohm.

Explanation:

We are given that:

The resistance of each resistor = 1/2

To Find: maximum resistance = ?

Solution:

Maximum resistance can be found when the resistors are conned in series combination.

Thus for series combination

Re = R1 + R2 + R3 + R4

Re 1/2 + 1/2 + 1/2 + 1/2

Re = 1 + 1 + 1 + 1 / 2

Re = 4 / 2

Re = 2 ohm

Thus the value of maximum resistance is 2 ohm.

Answer 2

Maximum resistance achievable by using the 4 resistors is 2 Ohms

Explanation:

Given: There are four resistors of 1/2 Ohm resistance each.

Find: Maximum resistance possible.

Solution:

Maximum resistance of more than one resistors can be achieved only when they are connected in a series form. We know that the total resistance of resistors in a series is given as:

R = R1 + R2 + R3 + R4 where R is the total resistance and R1, R2, R3 and R4 are the resistance of the individual resistors.

So let's substitute the values.

R = 1/2 + 1/2 + 1/2 + 1/2 = 2 Ohms

So the maximum resistance achievable by using the 4 resistors is 2 Ohms when in series connection.
