In the circuit shown in the image, the resistors that are connected in parallel (hliðtengd) are:

1. R2 and R3 are in parallel. These resistors are connected between points "a" and "b."
2. R4 and R5 are in parallel. These resistors are also connected between points "a" and "b."

The parallel configuration occurs when resistors share both endpoints. So, R2 and R3 share the same connection points at "a" and "b," and similarly for R4 and R5.

Would you like more details on how to calculate the equivalent resistance or any further explanation?

Here are 5 related questions:

1. How do you calculate the equivalent resistance for resistors in parallel?
2. How would you simplify this circuit step by step to find the total resistance?
3. What is the difference between series and parallel circuits?
4. Can you explain the formula used to calculate current in a parallel circuit?
5. What happens to the overall resistance when more resistors are added in parallel?

Tip: In parallel circuits, the total resistance is always less than the smallest individual resistor.
