Question

The maximum resistance which can be made using four resistors each of resistance ½ Ω

is

( a) 2 Ω (b) 1 Ω (c) 2.5 Ω (d) 8 Ω​

Answer 1

Answer:

1/2*4

= 2 ohms

a) is right.

Answer 2

Answer :

(a) 2 Ω ✔

Given :

• Four resistors each of resistance = ½ Ω

To find :

• maximum resistance which can be made using four resistors

Formula :

→ Resistance = R₁ + R₂ + R₃ + R₄

Here,

• R₁,R₂,R₃, R₄ =  ½ Ω

Solution :

⇒ Let's find the maximum resistance.

Resistance = R₁ + R₂ + R₃ + R₄

= 1/2 + 1/2 + 1/2 + 1/2

= 1 + 1 + 1 + 1/2

= 4/2

= 2

= 2 Ω

• Therefore, the maximum resistance which can be made using four resistors each of resistance is 2 Ω.
