To determine how many 650-Watt lights can be plugged into a standard 120-Volt, 1 outlet, we need to use the formula provided in the hint: . This formula represents the relationship between power (W), voltage (V), and current (I), where .First, let's calculate the current required for one 650-Watt light. We know that , so we can rearrange the formula to solve for current: .For one 650-Watt light: Now, we need to determine how many such lights can be plugged into the outlet. Since the outlet can supply 1 Ampere of current, we can divide the total current available by the current required for one light: Since we cannot have a fraction of a light, the answer is 0 lights. Therefore, none of the 650-Watt lights can be plugged into the standard 120-Volt, 1 outlet.
