If the voltage across the load is 20 volts and the current is 4 amperes, what is the power delivered to the load in watts?

Explanation:
To determine the power delivered to the load, you can use the formula for electrical power, which is P = V × I, where P is the power in watts, V is the voltage in volts, and I is the current in amperes. In this case, the voltage across the load is 20 volts and the current is 4 amperes. By applying the formula: P = 20 volts × 4 amperes = 80 watts. This calculation shows that the power delivered to the load is 80 watts, which aligns with the correct answer. Understanding this relationship between voltage, current, and power is fundamental in circuits, as it allows you to assess the energy consumption and performance of electrical devices.
