To find the calculated voltage in a DC circuit, Ohm's Law is applied, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R). In this situation, you have the current at 35 amperes and the resistance at 7 ohms.

Using the formula:

V = I × R

Substituting the given values:

V = 35 A × 7 Ω

This results in:

V = 245 volts

Thus, the correct answer is 245 volts. This demonstrates how Ohm's Law is used to determine the relationship between voltage, current, and resistance in a circuit. Knowing the values of current and resistance allows you to directly calculate the voltage, illustrating a fundamental principle that is essential in electronics and electrical engineering.
