Answer:
I= 27.09 A
Explanation:
Power of electric heater = 1500W= 1.50*10³ W
Power of toaster = 750W = 7.5*10²W
Power of electric grill = 1000W =1*10³ W
Voltage = 120V
By using formula P=VI ie I = [tex]\frac{P}{V}[/tex]
A) Current used by electric heater I₃ =[tex]\frac{1.50*10^3}{120}[/tex]
I₃ = 12.5 A
B) Current used by toaster I₂ =[tex]\frac{750}{120}[/tex]
I₂ = 6.25 A
C) Current used by electric grill I₃ = [tex]\frac{1000}{120}[/tex]
I₃ = 8.34 A
Current used by all three appliances is
I=I₁+I₂+I₃
I=12.5+6.25+8.34
I= 27.09 A
The current used by the three appliances is mathematically given as
I= 27.09 A
Question Parameter(s):
an electric heater is rated at 1500 W,
a toaster at 750 W,
and an electric grill at 1000 W.
Generally, the equation for the Current is mathematically given as
I=p/v
Therefore
[tex]I3 =\frac{1.50*10^3}{120}[/tex]
I=12.5A
[tex]I2 =\frac{750}{120}[/tex]
I2 = 6.25 A
[tex]I1 = \frac{1000}{120}[/tex]
I1 = 8.34 A
In conclusion, Current used by all three appliances is
I=12.5+6.25+8.34
I= 27.09 A
