# A single household circuit is connected to three electrical outlets (all in parallel). The outlets are connected to three devices. Will the 15-amp fuse of the circuit trip if all three appliances operate at the same time?

##
The devices are: an 800-W electric kettle, a 60-W trouble light, and a 1,000-W toaster oven.

Answer depend upon supply voltage

In USA supply is 110 volt.So current will be 16.9 amperes,It will trip. IN UK and Europe supply is 220. volt.Then current will be 8.45 amperes only.It will not trip total load= 1000+800+60=1860 watts..

To determine if the 15-amp fuse will trip, calculate the total current drawn by all three devices operating at the same time. For devices in parallel, the total current (I_total) is the sum of the individual currents (I_1, I_2, I_3) of each device:

[I_{total} = I_1 + I_2 + I_3]

Without the specific current or power ratings and voltage of the devices, we can't calculate the exact total current. However, if the sum of the currents drawn by the three devices exceeds 15 amps, the fuse will trip to prevent overloading the circuit.

For example, if each device draws 5 amps, the total current would be:

[I_{total} = 5A + 5A + 5A = 15A]

In this scenario, the fuse should not trip as the total does not exceed 15 amps. However, if any of the devices draws more current, or if there's additional current draw not accounted for, the total could exceed 15 amps, causing the fuse to trip. Always ensure the total current does not exceed the fuse rating for safety.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
