A copper wire of diameter 3.256mm carries a current of 6.25mA. the potential difference is mathematically given as
V=2.0657*10^{-4}
<h3>What is the potential difference across a 200m length of the wire?</h3>
Generally, the equation for is mathematically given as
R=Pl/A
Therefore
R=1.72*10^{-8}*2.00/\pi*(1.628)^2*10^{-6}
R=1.652*10^{-2}
In conclusion,
V=IR
V=12.5*10^{-3}*1.652*10^{-2}
V=2.0657*10^{-4}

For Newton's second law, the force experienced by the person is equal to the product between his mass and his acceleration:
Using
and
, the downward force is
Answer:
1 represents the electron flow
2 represents the load.
3 represents the voltage source.
4 represents the conductive path.
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
In an electrical circuit, there are various symbols used to represent different parameters or quantities as shown in the image attached above and these includes;
a. 1 represents the electron flow. This is a representation of the direction of flow of current.
b. 2 represents the load. This is the electrical appliance such as an electronic bulb that is being powered by the electrical circuit.
c. 3 represents the voltage source. This is typically a battery cell that provides the required amount of voltage for the circuit.
d. 4 represents the conductive path. This is the conductor that carries current from one point to another in the circuit such as copper.
