What is the difference between coulombs law and gravitation law?
Their mathematical forms are identical. The differences are: -- The proportionality constants. Newton's is 'G'. Coulomb's is 1/4Πε0 . -- The variables in Coulomb's numerator are electrical charges and he doesn't care about masses. The variables in Newton's numerator are masses and he doesn't care about charges. (I'm not sure Newton even knew about charges.) -- Coulomb's charges have a choice of two signs, so his forces can be attractive or repulsive, just like the co-eds in my sophomore engineering classes. Newton's masses are always positive, the gravitational forces are always attractive, and to this day negative mass has never yet been observed .
What has been recorded as the most basic unit of electrical charge?
The most basic unit of electrical charge is the charge of a single electron, which is approximately -1.6 x 10^-19 coulombs.
What are similarities and differences between Coulomb law and Newton's law of universal gravitation?
Coulomb's Law states: The magnitude of the electrostatic force between two point electric charges is directly proportional to the product of the magnitudes of each charge and inversely proportional to the square of the distance between the chargesNewton's Law of gravitation states: Every point mass attracts every other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses:Similarity: 1) Both apply the inverse-square law; intenity inversely proportional to square of the distance. 2) Talking about spherical objects i.e. point charge, point mass. Differences: 1) one is about large mass; one is about small size huge charges. 2) Gravitation is ONLY ABOUT attraction and NO repulsion. Coulomb's force has both attraction and repulsion
What is the mathematical form of coulombs law similar to?
Coulomb's law can be mathematically represented in a way similar to Newton's law of gravitation, where the force between two point charges is inversely proportional to the square of the distance between them and directly proportional to the product of the magnitudes of the charges. The formula for Coulomb's law is F = k * (q1*q2) / r^2, where F is the force between the two charges, q1 and q2 are the magnitudes of the charges, r is the distance between them, and k is Coulomb's constant.
What is the variable for coulombs?
The variable for charge in coulombs is typically represented by the letter "Q".
Is coulombs law a universal law?
No
How much charge does 12.5x1018 electrons have?
1.6x10^-19 coulombs/electron x 12.5x10^18 electrons = 20 coulombs
Give the electrical charge of electron?
The electrical charge of the electron is negative. Proton is positive Neutron is neutral Electron is negative
What is the definition of a current?
Current is electrical charge flow, in coulombs per second. We simplify coulombs per second and call it amperes.
What is electrical charge measured in?
Coulombs. 1 Coulomb = 6,241,510,000,000,000,000 electron or proton charges (rounded to the nearest 10 trillion)

What are the limitations coulombs law?
Limitations of coulombs law
What is moving electrical charges measured in amperes?
Charges, whether moving or not, are measured in coulomb, not in amperes.Amperes is the unit of current - coulombs per second.
What is the difference between volts and current?
Electrical current is the number of elementary charge units (coulombs) that pass by a given point in one second. Current, measured in amperes, is coulombs per second. Electrical voltage is the "pressure" behind that current. Voltage, measured in volts, is joules per coulomb.
Is resistance an opposition to electrical power and voltage is electrical pressure?
Resistance is an opposition to electrical currrent flow, which is more formally coulombs per second, or amperes. Voltage is electrical pressure, more formally joules per coulomb. When you multiply volts and amperes you get joules per second, or watts.
