WebKirchhoff’s 2 nd Law: As charge goes around the circuit the sum of EMFs must equal the sum of voltage drops leading to: E = IR + Ir The terminal voltage is equal to IR so this can be rearranged to give: V = E − Ir and interpreted as terminal voltage = EMF − lost volts Energy is conserved. Imagine a unit of charge, Q, moving around the circuit: WebFigure 1. The coil of a DC motor is represented as a resistor in this schematic. The back emf is represented as a variable emf that opposes the one driving the motor. Back emf is zero when the motor is not turning, …

WebMar 7, 2006 · No need to be sorry, you might be 100% correct. The lack of a core will alter the magnetic coupling coefficient, but if wound correctly, you can still get significant coupling, which will induce a back emf via the load current, which will change the overall emf values that the transformer stabilizes at.

What is Faraday
WebWhen flux changes, an emf is induced according to Faraday’s law of induction. Figure 1. (a) A motional emf = B ℓ v is induced between the rails when this rod moves to the right in the uniform magnetic field. The magnetic field B is into the page, perpendicular to the moving rod and rails and, hence, to the area enclosed by them.
