Answer:
The current in primary coil is 2.08 A.
Explanation:
Given that,
Power = 500 W
Voltage = 16 kV
Number of turns = 80000
We need to calculate the number of current
Using formula of voltage
Put the value into the formula
We need to calculate the current in secondary coil
Using formula of current
We need to calculate the current in primary coil
Put the value into the formula
Hence, The current in primary coil is 2.08 A.
Answer:
The correct answer is "".
Explanation:
According to the question,
Energy of satellite,
⇒
For the very 1st case:
or,
⇒ ...(1)
For the new case:
then,
⇒
...(2)
From equation (1) and (2), we get
⇒
D. Because as height increases, so does the potential energy.
