Examples of ampere in the following topics:

 The SI unit for measuring the rate of flow of electric charge is the ampere, which is equal to a charge flowing through some surface at the rate of one coulomb per second.
 Ohm's law can therefore be written as follows:
$I = V/R$
where I is the current through the conductor in amperes, V is the potential difference measured across the conductor in volts, and R is the resistance of the conductor in ohms (Ω).
 To solve this problem, we would just substitute the given values into Ohm's law: I = 1.5V/5Ω; I = 0.3 amperes.
 ampere (noun) A unit of electrical current; the standard base unit in the International System of Units.
Abbreviation: amp.
Symbol: A.
 ohm (noun) in the International System of Units, the derived unit of electrical resistance; the electrical resistance of a device across which a potential difference of one volt causes a current of one ampere; symbol:

 The force between currentcarrying wires is used as part of the operational definition of the ampere.
 For parallel wires placed one meter away from one another, each carrying one ampere, the force per meter is:
$\frac {F}{l}=\frac{(4\pi \cdot 10^{7} T \cdot m/A)(1A)^2}{(2\pi )(1m)}=2 \cdot 10^{7}N/m$
The final units come from replacing T with 1N/(A×m).
 Incidentally, this value is the basis of the operational definition of the ampere.
 This means that one ampere of current through two infinitely long parallel conductors (separated by one meter in empty space and free of any other magnetic fields) causes a force of 2×10^{7} N/m on each conductor.

 The SI unit for current is the ampere (A), which is equal to a coulomb per second (C/s).
 The SI unit for current is the ampere (A), named for the French physicist AndréMarie Ampère (1775–1836).
 Since I=ΔQ/Δt, we see that an ampere is one coulomb per second:
$1 \ A = 1 \ C/s$
The flow of electricity requires a medium in which charge can flow .
 An ampere is the flow of one coulomb through an area in one second.

 Capacitors are limited in their ability to prevent charge flow from one conductive surface to the other; their ability to hold charge is measured in Farads (F), which are defined as 1 amperesecond per volt, one joule per square volt and one Coulomb per volt, among other ways.

 permeability (noun) A quantitative measure of the degree of magnetization of a material in the presence of an applied magnetic field (measured in newtons per ampere squared in SI units).

 This law is founded on the conservation of charge (measured in coulombs), which is the product of current (amperes) and time (seconds).

 Considering loop abcdea, we can use Kirchhoff's loop rule:
$I_2R_2+ \mathrm{emf}_1I_2r_1I_1R_1=I_2(R_2)+r_1)+\mathrm{emf}_1I_1R_1=0$
Substituting values of resistance and emf from the figure diagram and canceling the ampere unit gives:
$3I_2+186I_1=0$
This is the second part of a system of three equations that we can use to find all three current values.

 The SI unit for magnitude of the magnetic field strength is called the tesla (T), which is equivalent to one Newton per amperemeter.

 For a straight current carrying wire that is not moving, the Lorentz force is:
$F=I\times L\times B$
where F is the force (in newtons, N), I is the current in the wire (in amperes, A), L is the length of the wire that is in the magnetic field (in m), and B is the magnetic field strength (in teslas, T).

 coulomb (noun) In the International System of Units, the derived unit of electric charge; the amount of electric charge carried by a current of 1 ampere flowing for 1 second.
