If the current is 3 amperes and the resistance is 45 ohms, what is the applied voltage in volts?

Explanation:
The applied voltage can be calculated using Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R). In this scenario, the current is given as 3 amperes and the resistance is 45 ohms. Using the formula V = I × R: - Multiply the current (3 A) by the resistance (45 Ω): V = 3 A × 45 Ω = 135 V Thus, the calculated voltage is 135 volts. This demonstrates the direct relationship between current, resistance, and voltage in an electrical circuit, confirming that when the current and the resistance are known, the voltage can be easily determined. Therefore, the correct answer reflects this calculation relationship accurately.

Using the formula V = I × R:

  • Multiply the current (3 A) by the resistance (45 Ω):

V = 3 A × 45 Ω = 135 V

Thus, the calculated voltage is 135 volts. This demonstrates the direct relationship between current, resistance, and voltage in an electrical circuit, confirming that when the current and the resistance are known, the voltage can be easily determined. Therefore, the correct answer reflects this calculation relationship accurately.
