Final answer:
To find the Thévenin voltage and resistance, add the series resistances for Rṫṕ and, if the total voltage is known, use Ohm's law for Vṫṕ. Without further details on the voltage or sources, we can only provide Rṫṕ.
Step-by-step explanation:
Calculation of Thévenin Voltage and Thévenin Resistance
To calculate the Thévenin voltage (Vṫṕ) and the Thévenin resistance (Rṫṕ) for a circuit containing two resistors in series with resistance values of 750 kΩ and 1.7 MΩ, we follow a systematic approach.
Step-by-Step Process
- Since the resistors are in series, calculate the total resistance (Rtot) by simply adding the resistances: Rtot = 750 kΩ + 1.7 MΩ.
- Use Ohm's law, which states V = I * Rtot, to find the total current (I) if the voltage (V) is given.
- To find the Vṫṕ, identify the open-circuit voltage across the load terminals when disconnected from any load.
- The Rṫṕ is the resistance seen from the load terminals with the voltage sources replaced by their internal resistances or short circuited if they are ideal voltage sources.
In this case, Rṫṕ would be the sum of the two resistors since no parallel connections or voltage sources are mentioned. Vṫṕ would depend on additional details not provided, such as the overall voltage of the system or the presence of any voltage sources.
