In alternating current (AC) systems, the movement of electric charge periodically reverses direction. AC is the form of electric power most commonly delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave, though certain applications use alternative waveforms, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. An important goal in these applications is recovery of i… WebThe current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point. In SI base units, the electric current density is measured in amperes per square metre.

WebThe magnetic force on a current-carrying wire in a magnetic field is given by F → = I l → × B →. For part a, since the current and magnetic field are perpendicular in this problem, we can simplify the formula to give us the magnitude and find the direction through the RHR-1. The angle θ is 90 degrees, which means sin θ = 1. WebThe left side represents the currents spilling outward and away from your floor, node V 1, and onto other nearby floors. (It cannot spill outward in opposition to current source I 1, since that current source is pointing into your node [floor.]) The right side represents the currents spilling inward and onto your floor from other nearby floors.
