Answer:
E = 1440 kJ
Explanation:
It is given that,
Power of a cooker oven is 800 W
Voltage at which it is operated is 230 V
Time, t = 30 minutes = 1800 seconds
We need to find the electrical energy used by the cooker oven. The product of power and time is equal to the energy consumed. So,
So, electrical energy of 1440 kJ is consumed by the cooker oven.
A) We need to calculate the Magnetic flux of a Solenoid,
Where B is the magnetic field and A the Area.
Here \mu_0 is the permeability constant, I the current and N number of turns.
Replacing we have,
B) We calculate the mutual inductance, so
c) We calculate the emf
