The flow of current through a metallic conductor creates a magnetic field around the conductor. The magnetic field is oriented perpendicularly to the direction of the current flow. The strength of this field is inversely proportional to the distance away…

In a series circuit, the current is constant around the circuit and total resistance is the sum of individual resistances which can be calculated as: RTotal = R1 + R2 + R3 + Rx…. In the series circuit, the voltage…

Ohm’s Law postulates that current is directly proportional to an applied voltage and inversely proportional to resistance. This is expressed as: Current = Voltage/Resistance, or I=V/R, which can be transposed to get; V=IR R=V/I NB: Volts push Amps through Ohms.…

The only particle that moves when an electric circuit is completed is the electron. For this reason, electricity is described as the flow of electrons. In the atom, there are 3 fundamental particles – proton, electron, and neutron. The proton…
