Final answer:
General purpose outlets are typically rated for a safe operation at around 15 amps. The sum of currents drawn by an 1800-W toaster (15 A), a 1400-W speaker or electric frying pan (11.67 A), and a 75-W lamp (0.625 A) plugged into the same 120-V circuit exceeds the 15-A limit of the fuse, indicating that this combination of devices would blow the fuse.
Step-by-step explanation:
The question asks about electrical loads for outlets in general purpose applications. According to electrical safety regulations, individual outlets should not be considered to have a load of less than a specified amount of current, typically indicated in amperes (or amps). Standard outlets have a certain rating, commonly around 15 amps, for safe operation. Overloading an outlet can lead to a risk of blowing a fuse or tripping a circuit breaker.
Calculating the Current Drawn by Each Device
To calculate the current drawn by each device, use the formula:
I = P/V
- 1800-W toaster: I = 1800 W / 120 V = 15 A
- 1400-W speaker or electric frying pan: I = 1400 W / 120 V = 11.67 A
- 75-W lamp: I = 75 W / 120 V = 0.625 A
Assessing the Fuse Capacity
If we add up the current drawn by these devices, the total would exceed the maximum of 15 amps allowed by the circuit, likely causing the fuse to blow.
