Question:
1.- The inductance of a coil whose resistance is 65 is 25H. The coil is connected to a 50V battery through a switch. How long does it take for the current in the coil to reach half its equilibrium value? For this value of t, state the rate of change.
2.- The diagram shows an R-C circuit with a "power source" of 100 volts(rms), at 60 Hz. If a student measures 80 V across the capacitor, what voltage will he observe for the resistor?
\fUn circuito electrico contiene una pila o bateria con FEM 6, y un resistor con resisten- cia R, longitud ] y masa m, que puede moverse lateralmente con libertad, segun se indica en la siguiente figura. Como se ilustra, hay un cam- po magneticc uniforme B perpendicular al pla- no del circuito. Cuando se cierra el interruptor S, puede suponerse que la corriente en R es 1/Rent = 0. Demuestre que la corriente indu- cida esta dada por lind = 61'/ B'1/(mR?), a con- dicion de que : no sea demasiado grande. Indi- que lo que sucede para un valor grande de t.
