How can 2230Ω be expressed?

To understand how 2230Ω can be expressed in kilohms, it's important to know the relationship between ohms and kilohms. One kilohm (kΩ) is equal to 1000 ohms (Ω). Therefore, to convert ohms into kilohms, you divide the number of ohms by 1000.

For 2230 ohms, the calculation would be:

2230Ω ÷ 1000 = 2.23 kΩ.

This denotes that 2230 ohms is equivalent to 2.23 kilohms, making this the correct expression for the value given. Understanding this conversion is key in electrical engineering and maintenance contexts where units often need to be changed for clarity or convenience.

The other options represent incorrect conversions based on miscalculations or misunderstandings of magnitude when converting from ohms to kilohms.
