Answer: 1A
Explanation: for an ideal transformer, the relationship between number of turns and current is given below as
Ip/ Is = Ns/ Np
Where Ip = current in primary loop = 3A
Is = current in secondary loop =?
Np = number of turns in primary loop = n
Ns = number of turns in secondary loop = 3n
By substituting the parameters, we have that
3/Is = 3n/n
3/Is = 3
3 = 3 × Is
Is = 3/3 = 1A
Current in the secondary loop is 1A
This is an example of state change from solid to liquid.
Answer:
C has the greatest capacitance and the lightest load. It will provide current to the load for the longest.
A & E are the same
B is next, and finally
D has the smallest equivalent capacitance and the heaviest load. it will run out of juice the quickest.
Curious that the pictures are out of alphabetic order A B C E D.
