Using OHM's law, if the current is 35 amperes and the resistance is 7 ohms, what is the voltage?

• A. 70 Volts
• B. 245 Volts
• C. 5 Volts
• D. 49 Volts

Answer: (B)

To find the voltage using Ohm's Law, you use the formula: Voltage (V) = Current (I) × Resistance (R). In this case, the current is given as 35 amperes and the resistance is 7 ohms. By substituting the values into the formula: \[ V = 35 \, \text{amperes} \times 7 \, \text{ohms} \] This results in: \[ V = 245 \, \text{volts} \] Thus, the calculated voltage is 245 volts, which confirms that the correct answer is indeed the choice indicating 245 volts. This demonstrates how Ohm's Law effectively relates current, resistance, and voltage in an electrical circuit, providing a foundational concept in electrical engineering and maintenance practices.

To find the voltage using Ohm's Law, you use the formula: Voltage (V) = Current (I) × Resistance (R). In this case, the current is given as 35 amperes and the resistance is 7 ohms.

By substituting the values into the formula:

[ V = 35 , \text{amperes} \times 7 , \text{ohms} ]

This results in:

[ V = 245 , \text{volts} ]

Thus, the calculated voltage is 245 volts, which confirms that the correct answer is indeed the choice indicating 245 volts.
