16 miles per hour? I dont really understand your question
Answer:
No they are totally different...
Velocity is displacement/time. while vector is both magnitude and direction.....
Velocity is a vector quantity because it has both magnitude and direction
Answer:
Number of turns in secondary is 20
Current in primary is 0.96 A
Explanation:
We have given number of turns in primary
Voltage across primary of transformer
Current in secondary coil
Voltage across secondary
For transformer we know that
So
So number of turns in primary is 20
Now
Current in primary of transformer is 0.96 A
When the key is off there should be no current in the circuit.
Our ammeter still measures some current, and this is called hysteresis error. This means that this particular ammeter is going to add some amount of current to any current measured. In order to compensate for this error, we simply we deduct it from all measurements.
Each mark on the ammeter is worth:
This means that our error is:
When the circuit is closed we measure:
This is current with the error, real current in the circuit is:
