Final answer:
The correlation between volts, amperes, and wattage is described by the expression P = IV, where power is equal to current multiplied by voltage.
Step-by-step explanation:
Electric power is the rate at which energy is used or converted in an electric circuit. The expression for electric power is P = IV, where P is power in watts, I is current in amperes, and V is voltage in volts. This means that power is equal to the product of current and voltage.
When voltage is increased, power also increases. For example, when a 25-Watt bulb designed for 120 volts is connected to 240 volts, its power nearly quadruples to about 100 watts, causing it to burn out. Similarly, if the resistance connected to a given voltage source is lower, the power delivered is greater.
Therefore, in summary, the correlation between volts, amperes, and wattage can be described by the expression P = IV, where power is equal to current multiplied by voltage.
