What is the variable for coulombs?
The variable for charge in coulombs is typically represented by the letter "Q".
What does q stand for in physics?
q is just a variable name. It represents different things in different equations around the world.
What are the fundamental units of q in physics?
In physics, the fundamental units of charge (q) are measured in coulombs (C).
An electric bulb draws a current of 0.25A for 20 minutes calculate the electric charge?
1 Ampere = 1 Coulomb per second0.25 A = 0.25 Coulomb per sec1 minute = 60 seconds20 minutes = (20 x 60) = 1,200 seconds0.25 A for 20 minutes = (0.25 x 1,200) = 300 Amp-seconds = 300 Coulombs of charge

Is coulombs law a universal law?
No
What mathematical expression identifies the number of coulombs necessary to produce one mole of iron metal from an aqueous solution of iron III sulfate?
The mathematical expression is Q = nF, where Q is the total charge in coulombs, n is the number of moles of electrons transferred (in this case, 3 moles for iron III sulfate to iron metal), and F is the Faraday constant (96,485 C/mol). Therefore, the number of coulombs necessary would be Q = 3 * 96485 C/mol = 289,455 C.
How is coulombs law different from newton law?
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
What are the fundamental units of q in physics?
In physics, the fundamental units of charge (q) are measured in coulombs (C).
What is a faraday?
The main use of a Faraday is in the formula Q=nF. If this is rearranged, F=Q/n A Faraday is 96485 coulombs.
How do you calculate electrostatic force?
coulombs law
What current Must flow if 0.24 coulombs is to be transferred in 15Ms?
For a steady flow of charge through a surface, the current I in amperes can be calculated with the following equation:I = Q/t where Q is the electric charge transferred through the surface over some time t. If Q and t are measured in coulombs and seconds respectively, I is in amperes. Thus: I = 0.24 coulombs / 15 msec I = 0.24 coulombs / 15 * 10^-3 sec I = 16 amps
How many amps is 1000 coulombs?
To calculate the amperes when given coulombs, use the formula: Current (I) = Charge (Q) / Time (t). If the time is not specified, you can't determine the current from just the charge in coulombs.
