An increase in voltage typically results in what kind of change to the power in an electrical system?

• A. Decrease of power
• B. Increase of power
• C. No effect on power
• D. Power becomes negative

Answer: (B)

An increase in voltage in an electrical system typically leads to an increase in power, assuming other factors such as resistance remain constant. This relationship is described by the power formula, which states that power (P) is equal to voltage (V) multiplied by current (I), represented mathematically as P = V × I. When voltage increases while the current remains constant, the power must increase proportionally. This is because the power is directly related to the amount of voltage supplied to the system. In other scenarios, if the resistance within the circuit remains unchanged, Ohm’s Law (V = I × R) also implies that an increase in voltage will result in an increase in current, further contributing to the increase in power consumption. Thus, when assessing the effects of voltage changes on power, it becomes clear that an increase in voltage significantly impacts the system by elevating the power output, thereby making the assertion that power increases with voltage change accurate.
