Step 1:
R_{ohms} = 7.4 imes 1000
The multimeter reading of 7.4 kΩ needs to be converted to ohms. In this context, the prefix "k" stands for kilo, which is a factor of 1000. Therefore, we need to multiply the resistance in kΩ by 1000 to get the value in ohms.
Step 2:
R_{ohms} = 7400
Perform the multiplication to find the resistance in ohms.
Final Answer
The value of the resistance is 7,400 ohms (option D).
