If the transformer’s primary coil has 20 times as many turns of wire in it as the secondary coil has, then the secondary coil provides a small voltage rise for the large amount of current that flows through it.
Answer: Option B
<u>Explanation:</u>
A transformer has a two types of coils, the first one is primary coils and the second one is secondary coil. A secondary coils with hardly any turns in it provides the charges going through it just limited quantities of energy.
Without a long separation over which to do chip away at the charges streaming in the loop, the transformer delivers just a little ascent in the voltage of those charges. Be that as it may, the coil can give this little voltage to ascend to a huge current without requiring an excess of power supply from the input circuit.
The total charge transferred is
. This total charge consists of N electrons, each one with charge
. To find N, the number of electrons transferred, we must simply divide the total charge by the charge of a single electron:
Answer:
True
Explanation:
Distance is defined as the length of the actual path traveled by the body.
Displacement is defined as the minimum distance between the two points.
the magnitude of displacement is always less than or equal to the distance traveled by the body.
As a deer runs from A to b , so it means the distance traveled by the deer is either equal to the magnitude of displacement or always greater than the magnitude of displacement of the deer.
Displacement can never be greater than the distance.
Thus, the option is true.
Metals Non-metals
They are solid at room temperature. They may be solid, liquid and gas at room temperature.
They have high melting and boiling points. They have low melting and boiling points.
They are good conductors of heat and electricity. They are bad conductors of heat and electricity.
SI units for volume don't care whether you use them to describe
a solid, a liquid, a gas, or a volume of vacuum.
The units are the liter, and the cubic meter (1,000 liters).
