Question

Two resistors of 2Ω each are connected in parallel. The equivalent resistance is:

Options

• less than 2Ω but more than 1Ω

• one ohm

• four ohm

• between 4⁢Ω and 2⁢Ω

Answer 1

One ohm

Explanation:

For two equal resistors in parallel,

$$R_p = \frac{R}{n} = \frac{2}{2} = 1\Omega$$

Therefore, the equivalent resistance is one ohm.
