Final answer:
The total resistance between terminals 1 and 2 of the series circuit is 2.45 MΩ.
Step-by-step explanation:
In a series circuit, the total resistance is equal to the sum of the individual resistances. To find the total resistance, we add the resistance values of the two resistors: 750 kΩ and 1.7 ΜΩ.
Converting the units to a common base, we have 750 kΩ = 0.75 MΩ and 1.7 ΜΩ = 1700 kΩ.
Adding the resistances, we get 0.75 MΩ + 1700 kΩ = 0.75 MΩ + 1.7 MΩ = 2.45 MΩ.
Therefore, the total resistance between terminals 1 and 2 of the circuit is 2.45 MΩ.
