Answer:
E= 11400000
Explanation:
power=energy/time
Making energy the subject
energy=power x time
power=3800
time=50 x 60 =3000
E=p x t
E=3800 x 3000
Energy= 11400000
The energy it uses in 50 min will be 11.4× 10⁶ J.
Electric power is the product of voltage and current. Its unit is the watt. It is the rate of the electric work done.
Unit conversion;
1 min = 60 sec
The given data in the problem is;
The electric power is, P = 3,800 W
Time period is,t = 50 min = 50 × 60 second = 3000 sec
E is the energy=?
The electric power is found as;
P=E/t
E = P × t
E= 3800 x 3000
E = 11.4× 10⁶ J.
Hence the energy it uses in 50 min will be 11.4× 10⁶ J.
