What is the current flowing through a 12volt battery that has 3ohm resistor that is attached to a dc circuit?
I=v/r, then 12/30=4/10=0.4amp
Can I replace a 12volt dc 2amp adaptor with a 12volt 1.5 dc adaptor?
by definition the wattage is the criteria 12v x 2amps=24 watts If the circuit in question needs 2 amperes then an exactreplacement mandatory, however if the circuit in question only draws 1.5 amps then it is realistic possible
How much is 100ah is equal to?
Commonly this figure is used for battery used for cars or UPS. 100Ah means, you can draw 100 Ampere current for one hour. Like a battery 0f 12Volt,7Ah can be used for a circuit which draw current of 1 Amp. can be used for approximately 7 hours.
How do you charge a 12volt battery from a 220volt home system?
With a 12 volt battery charger that is made to plug into a 220 volt circuit.
What is the current in a 12volt circuit that has 9 ohms of resistance?
Ohm's Law: Current equals voltage divided by resistanceIf the two 3 ohm resistors are in series, then 12 volts divided by 6 ohms is 2 amperes.If the two 3 ohm resistors are in parallel, then 12 volts divided by 1.5 ohms is 8 amperes.WARNING: In the first case, this is 24 watts or 12 watts per resistor. In the second case, this is 96 watts or 48 watts per resistor. Exercise great care if you intend to duplicate this in the lab, i.e. do not think for even a split second that a 1/4 watt resistor is going to be able to handle this power without burning up and causing a fire.
Why you use transformer in clap switch and why not battery?
A device used to transfer electric energy from one circuit to another, especially a pair of multiply wound, inductively coupled wire coils that effect such a transfer with a change in voltage, current, phase, or other electric characteristic.The relay contact is connected to the power line and hence turns on/off any electrical appliance connected all the way through relay.For power supply, we have made 12Volt eliminator with the help of Transformer T1, Diode D1 and capacitor C1.It is a half wave rectifier.
Can a 9 volt adaptor be used on a appliance that calls for 9volt battery or 12volt adaptor?
No. The person who designed your appliance had a 12v adapter, so when he designed the adapter connector he put a resistor in it to drop the voltage to 9v.
How do you check amps with a mutimeter?
First be sure to have it on, And on the 12volt setting (if selectable) Be sure to get a good grounding point, I.E, door hinge, Seat bolt, Batt ground, Then just touch the other end (Red) to the point your testing volts. It should then give you your reading, Just be sure not to confuse the wires, Damage your testing unit or worse, Short cars wiring. Hope that helps!Answer 2:An ammeter needs to be connected in series with your circuit, (that is, all current must "check in" at the ammeter). Many ammeters are called multimeters because they are both ammeters (measuring current) and voltmeters (measuring voltage). many people make the mistake of setting the multimeter up such that it is reading voltage when they desire to read current.When a voltmeter is hooked up in series with a circuit, the fuse within the voltmeter may break, sufficiently pissing off any lab instructor you may be working under.
Can you charge a 75volt battery with a 12volt charger?
No.
Can you replace a 12volt alternator with a 24volt alternator?
You can if you plan to convert all of your electrical system, starter, lights, gauges and accessories to 24 also. And change your battery to 2 batteries connected in series. Why would you want to??
Is the pink wire positive and the black wire negative?
Yellow= Constant +12volt Red= Switched +12volt Black= -12volt or ground Blue= remote Blue/White= power antenna Pink or Orange= wire color depends on brand but is the dimmer for lights.
How do you divide 12 volt 5 amp in 4 cameras of 12volt 0.5 amp?
What determines the current is the load. So voltage is the important factor. The voltage is the same. So you only conect up to ten cameras and the current is ok. They will work fine.
