Answer:
a) Current drawn by the toaster = 15A
Current drawn by the electric frying pan = 11.67A
Current drawn by the lamp = 0.625A
b) This combination will blow the 15A fuse as the total current requirement for this setup exceeds the 15A rating of the fuse.
Explanation:
a) For parallel connection, there exists, the same voltage and different currents across all the devices.
Voltage cross each of the 3 devices = outlet voltage of 120V
From their respective power rating, current drawn by each device will be calculated.
P = IV
For the toaster, P = 1800 W, V = 120V
I = 1800/120 = 15A
For the electric frying pan, P = 1400 W, V = 120 V
I = 1400/120 = 11.67 A
For the lamp, P = 75 W, V = 120V
I = 75/120 = 0.625 A
b) Total current in a parallel connection setup = Sum total of all the currents.
Total current drawn by all 3 devices = 15 + 11.67 + 0.625 = 27.295A = 27.3 A
This total current requirement surpasses the 15A current rating of the fuse, therefore, this combination will blow the fuse.
Hope this Helps!!!
