dc source การใช้

• DC to AC converters produce an AC output waveform from a DC source.
• DC calculating boards used resistors and DC sources to represent an AC network.
• The constant voltage source is obtained by connecting a large capacitor across the DC source.
• I-V curves are used to characterize devices and materials through DC source-measure testing.
• Many electrical workers have been jolted by various AC and DC sources and lived to tell about it.
• Once the DC source is removed the capacitors will provide the magnetization current required to begin producing voltage.
• If both switches in a leg were on at the same time, the DC source will be shorted out.
• The cascaded has the disadvantage to need separate DC sources but circuit layout is compact and voltage sharing problem is absent.
• In this type of inverter, a constant current source is obtained by connecting a large inductor in series the DC source.
• When the operational amplifier's input bias currents are significant, then the DC source resistances driving the inputs should be balanced.
• Pulsating currents are commonly the consequence of using diode rectifiers, or DC sources of lower amplitude connected in series with AC sources.
• :: : If you simply power an LED from a DC source, you're right-they don't strobe.
• The power was provided from a 2 kW at 3.8 kV, with polarization from a 20 V / 8 A DC source.
• An induction machine can be started by charging the capacitors, with a DC source, while the generator is turning typically at or above generating speeds.
• With a DC source, you will charge the capacitor, giving it some energy in a period of time ( that is, at a certain power ).
• If the voltage between the DC source and the first resistor ( 67 ohms ) is measured, the voltage potential at the first resistor will be slightly less than nine volts.
• But I agree that it is almost certainly the other meaning : " directly from the battery-not indirectly through a dynamo " because early sources of AC would have come indirectly from some ultimate DC source.
• :: The term voltage stabilizer usually applies to an ac source, whereas voltage regulator usually applies to control of a dc source .-- talk ) 21 : 03, 27 June 2010 ( UTC)
• In this form of biasing, the base resistor R _ { \ text { B } } is connected to the collector instead of connecting it to the DC source V _ { \ text { cc } }.
• Manufacturers are required by EU law to display power " at full setting of the power controller " ( from an external DC source when performing laboratory vehicle approval ), but not necessarily to show power limited by battery.
