What is the relationship between voltage, current, and resistance in terms of energy consumption?

• A. Higher resistance leads to higher energy consumption
• B. Higher voltage and current increase energy consumption
• C. Lower voltage and current increase energy consumption
• D. There's no effect between these variables and energy consumption

Answer: (B)

The relationship between voltage, current, and resistance is described by Ohm’s Law, which states that the current flowing through a conductor between two points is proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. The power (or energy consumption) in an electrical circuit can be calculated using the formula: Power (P) = Voltage (V) × Current (I). When both the voltage and current are higher, the product of these two values increases, resulting in greater energy consumption. This means that if either voltage or current increases, the overall power—hence energy consumption—also increases, reflecting an increase in the rate at which energy is used in the circuit. Choosing this option highlights the direct relationship between voltage, current, and energy consumption, illustrating that both factors positively impact energy usage when they increase simultaneously. Lower voltage and current would generally lead to lower energy consumption because the formula indicates that reducing either value would decrease the power. Thus, higher voltage and current indeed correlate with increased energy consumption, making this answer correct.
