Answer:
The number of turns in secondary coil is 4000
Explanation:
Given:
Current in primary coil A
Current in secondary coil A
Number of turns in primary coil
In case of transformer the relation between current and number of turns is given by,
For finding number of turns in secondary coil,
Therefore, the number of turns in secondary coil is 4000
Answer:
Q = 1.2*10⁻¹² C
Explanation:
- For any capacitor, by definition the capacitance C is equal to the relationship between the charge on one of the conductors and the potential difference between them, as follows:
- For the special case of a parallel plate capacitor, just by application of Gauss' law to a rectangular surface half out of the outer surface, and half inside it, it can be showed that the value of the capacitance C is a parameter defined only by geometric constants, as follows:
- So, due to the left sides in (1) and (2) are equal each other, right sides must be equal too.
- Replacing ε₀, εr (dielectric constant), A, d and V by their values, we can solve for Q, as follows:
