Yes. The first generation of op amps worked from +15 and -15 volt supplies.
You can now get low-voltage and micropower op amps that work on single supplies, and on low-voltage supplies.
Look for:
low power op amp
on the web, or check out your local electronics store - one that actually sells parts, not just equipment.
What else can I help you with?
How an op amp differs from a basic amp?
A basic, single transistor amplifier differs from an op amp: 1. The op amp has more gain 2. The op amp may have higher input resistance (so it loads the circuit less) 3. The op amp may have a lower output resistance (so it can drive larger currents) 4. The op amp likely has a lower frequency response (due to the high gain, unless you provide some sort of feedback loop) 5. The op amp is ridiculously complex compared to a simple amplifier 6. The op amp will require a positive and negative voltage (may be unnecessary with a single transistor amplifier)
Is it okay to use a 12 volts 600 milliamp DC power supply with a device that says it needs 12 volts 1 amp?
No, 1 amp is 1000 milliamp your power supply will only deliver 600 milliamp or .6 of an amp.
What voltage will you get adding 2 solar panels of 18V 3 amp and 12V 3 amp if you connect them parallel should you get 6 amp not sure on voltage though does it drop to 12v?
yes, it is 12 volts
How do you hook up 12 volts lights using 6 6 volt batteries?
Use a series parallel configuration. Two batteries in series to get the 12 volts. Three parallel banks of two batteries to get an increase of amp hours.
What size breaker is needed for 208 volts 6 amps using Ohm's law?
20 amp In North America code states a two pole 15 amp breaker will do the job.
Can you use two 6 amp chargers on one battery at the same time?
No, you would be applying 24 volts to the 12 volt battery.
I have a hurricane lamp with a 6v 6 amp rechargeable battery that no longer holds a charge and wonder can I substitute a rechargeable 6v 12 amp battery?
Yes you can. The battery supplies only as much current (amps) as the lamp draws when connected to 6 volts. The "12 amp" battery won't supply any more current when the lamp is shining than the "6 amp" battery did, but it'll last twice as long between charges.
How many watt DC to AC converter do you need to run a 6 amp power tool?
The formula for watts (or power) is Amps times voltage. Therefore with a 6 amp draw times 120 volts would be about 720 watts. A 1000 watt power inverter would do the job.
6 watts is how many amps 24vdc?
For a resistive load Watts = Volta * Amps. Therefore, you have 1/4 amp or 250 Milliamps (250ma)
DC voltage of 120 volts is feeding series circuit consisting of 2-ohm 6-ohm and 8-ohm regular resistors a variable resistor For line ammeter to indicate 1.5 amp the variable resistor must be fixed?
If the DC voltage of 120 volts is feeding series circuit consisting of 2-ohm, 6-ohm, and 8-ohm regular resistors, the variable resistor for line ammeter to indicate 1.5 amp, the variable resistor must be fixed before the amp.
Is a marine battery 12 volts or 6 volts?
12 volts
Can 6 unit of 6 volt bulb fit a 13 amp plug?
No, a 13 amp plug is designed for higher power devices like appliances and electronics. A 6 unit of 6 volt bulb typically requires much less power and would be better suited for a lower amp plug or a transformer.
