Answer:
a ) 3 v
b ) 400 mA
Explanation:
In case of transformer there is relation between no of turns in primary and secondary coils and voltage input and output as follows
V₁ / V₂ = n₁ / n₂
Where V₁ and V₂ are input and output voltage and n₁ and n₂ are no of turns of primary and secondary coils.
Here V₁ = 1.5 v , V₂ = ? , n₁ = 10 , n₂ = 20
Put the values in the equation above
1.5 / V₂ = 10 / 20
V₂ = 3 v.
Similarly formula for current is as follows
I₁ / I₂ = n₂ / n₁
Whereas I₁ and I₂ are current in primary and secondary coil
Put the values in the equation above
I₁ / 200 mA = 20 / 10
I₁ = 400 mA.
AnswerIt is continuously falling towards the surface of the earth
Explanation:
since gravity from earth is the thing that keeps it constantly in orbit
A negative charge i guess
