Given the size, shape and material of a conductor, what else would you need in order to find the current through the conductor?
1 answer:
Explanation:
The number of charges flowing per second inside the conductor is called the current through the conductor. Mathematically, it is given by :
Where
Q is the charge
t is time
Since, Q = ne
n is number of electrons
e is the charge on one electron
So, to find the current through the conductor we must know the number of electrons moving per second through it. Hence, this is the required solution.

Explanation:
Given that
At starting separated = 1.20m
And the increase in background noise by Δβ = 5 dB, due to which the level of sound also rises
Based on the above information, the separation rf that is needed is shown below:
As we know that
Hence, the separation r_f i.e. required is
We simply applied the above equation so that the correct separation could come
Answer:
I amperes
Explanation:
Newton is the unit of force. Hence 4 newton is not the current “I”
Joules is the unit of energy and hence it do not signify current I
Watt is the unit of power i.e the rate of transfer of energy.
Ohm is the unit of resistance produces thereby obstructing the flow of current
And Volts is the unit of voltage or potential difference between two ends of an electric circuit. Thus, it is also does not signifies current.
Thus, I amperes
