Question

find equivalent resistance between A and B​

Answer 1

Answer:

0.5 ohmwe must use resistance in parallel formula.

Answer 2

Answer:

1/2 ohm = 0.5 ohm

Step-by-step explanation:

Equivalent resistance between the two resistors of 2 ohm each:

$\tt{\frac{1}{R} = \frac{1}{R_{1}} + \frac{1}{R_{2}}}$

$\tt{\frac{1}{R} = \frac{1}{2} + \frac{1}{2}}}$

$\tt{\frac{1}{R} = 1}$

R = 1 ohm

Similarly, equivalent resistance of other setup of two 2 ohm resistors = 1 ohm

These two are connected in parallel, thus, equivalent resistance:

$\tt{\frac{1}{R} = 1 + 1}}$

=> R = 0.5 ohm
