5J20.00LR Circuits
5J20.10RL time constant on scopePIRA 200Show the RL time constant on a scope.
5J20.10LR time constant on scope5J20.10The current and voltage of an slow time constant LR circuit are displayed on a dual trace storage oscilloscope.
5J20.10L/R time constantEo-11A plug in circuit board with a make before break switch for showing slow RL time constants on the oscilloscope.
5J20.10RL time constantEn-6The RL time constant is shown on a scope.
5J20.11time constant of an inductive cir.En-7Compare the time constant of an inductor using different cores on an oscilloscope.
5J20.20lamps in series or parallel with ind.PIRA 200Hook light bulbs in series with a large electromagnet.
5J20.20current in an inductive circuitEn-5Light bulbs across and in series with a large electromagnet show the current in an inductive circuit.
5J20.20lamps in series and parallel on EM31-3.5Two lamps are used to indicate voltage across and current through a large electromagnet.
5J20.20series lamps on an EME-12cLight bulbs are hooked up in series with a large electromagnet.
5J20.20lamps in parallel with solenoidDisc 21-03Apply 110 V to a large solenoid with incandescent and neon lamps in parallel. The neon lamp flashes on the opposite side on discharge.
5J20.21lights in series and parallel31-3.1A circuit with a 5 H inductor has neon lamps in series and in parallel.
5J20.25inductor characteristics33-5.1A bulb in parallel with a coil does not burn when powered by dc, but does when coupled to a high frequency source.
5J20.30LR time constantE-257Substitute a inductor and resistor of the same R in a circuit that lights a neon bulb.
