PhysicsEasysingle choice

By using only two resistance coils singly, in series or in parallel one should be able to obtain resistances of $3$ , $4$ , $12$ and $16 Ω$ . The separate resistances of the coil are

Options:

Answer:

Solution:

If we take $R_{1} = 4 Ω$ , $R_{2} = 12 Ω$ then in series resistance

$R = R_{1} + R_{2}$

$= 4 + 12$

$= 16 Ω$

In parallel, resistance $R = \frac{4 \times 12}{4 + 12} = 3 Ω$

$So R_{1} = 4 Ω$ , $R_{2} = 12 Ω$
