Ohm is the reciprocal of Siemens. Ohm = 1/Siemens.
Multiple subs wired together must be the same coil type and impedance. If they’re not, the power won’t divide evenly between them, and some subs would probably be over-powered while others get under-powered. If you want to run different types of subs in a system, each type needs to have its own separate amp. Then, multiply the number of subs you have by the RMS rating of each, to get their total RMS rating. You want to make sure the amp you choose will supply no more than the sub system’s total RMS rating. Figure out the possible total impedance(s) that the subs can be wired together to form. (SVC = single voice coil, 1 pair of terminals; DVC = dual voice coil, 2 pairs of terminals.) 1 SVC 2-ohms can only have 2 ohms of impedance 1 SVC 4-ohms can only have 4 ohms of impedance 1 DVC 2-ohms can have 1 ohm or 4 ohms of impedance 1 DVC 4-ohms can have 2 ohms or 8 ohms of impedance 2 SVC 2-ohms can have 1 ohm or 4 ohms of impedance 2 SVC 4-ohms can have 2 ohms or 8 ohms of impedance 2 DVC 2-ohms can have 2 ohms or 8 ohms of impedance 2 DVC 4-ohms can have 1 ohm or 4 ohms of impedance 3 SVC 2-ohms can have 6 ohms of impedance 3 SVC 4-ohms can have 1.3 ohms of impedance 3 DVC 2-ohms can have 1.3 ohms or 3 ohms of impedance 3 DVC 4-ohms can have 2.7 ohms or 6 ohms of impedance 4 SVC 2-ohms can have 2 ohms or 8 ohms of impedance 4 SVC 4-ohms can have 1 ohm or 4 ohms of impedance 4 DVC 2-ohms can have 1 ohm or 4 ohms of impedance 4 DVC 4-ohms can have 2 ohms or 8 ohms of impedance Look for an amplifier that can put out power up to the RMS wattage at an impedance load the subs can be wired to form. 8 ohms — figure on the amp putting out half the power it would at 4 ohms 6 ohms — figure on the amp putting out three-quarters of the power it would at 4 ohms 3 ohms — figure on the amp putting out the average of what it would at 2 ohms and at 4 ohms 2.7 ohms — figure the same as for 3 ohms, and add a few watts 1.3 ohms — use the 1-ohm spec and take away a few watts Example: You have two Alpine S Series S-W8D4 8" subwoofers and you want the right amp for them. They are DVC 4-ohm subs rated at 300 watts RMS each. Two 300 watts RMS subs together need a maximum total of 600 watts RMS. Using the chart in Step 2, 2 DVC 4-ohm subs can be wired together to form a 1-ohm, a 4-ohm, or a 16-ohm load. The last is too high a load to be practical, so you’ll look for an amp that can put out up to 600 watts RMS into either a 4-ohm load, or a 1-ohm impedance load: up to 600 watts RMS x 1 at 4 ohms, or up to 600 watts RMS x 1 at 1 ohm Among Crutchfield’s selection of amplifiers you’ll find: Memphis Audio PRXA600.1 — 600 watts RMS x 1 at 1 ohm JL Audio JD1000/1 — 600 watts RMS x 1 at 4 ohms Kicker KEY500.1 — 500 watts RMS x 1 at 1 ohm Any one of these high-quality amplifiers would work well with those subs. It doesn’t matter which impedance an amp plays through — 600 watts RMS through a 4-ohm load produces the same volume as 600 watts RMS through a 1-ohm load. You have a Memphis Audio SRX500D.1 amplifier and you want it to drive two subwoofers The amp is capable of 350 watts RMS x 1 at 4 ohms and 500 watts RMS x 1 at 2 ohms. Let’s say you choose to maximize the amp’s potential and want the system to put out 500 watts RMS. This means your subs have to be wired to form a total impedance of 2 ohms. Two subs on a 500 watts RMS amp will want about 250 watts RMS each. So you’ll look for subs each rated for 250 watts RMS or more. Using the chart in Step 3, for two subwoofers, a final 2-ohm load can be achieved with either two SVC 4-ohm subs or two DVC 2-ohm subs. So, you’ll look for two subs that are either SVC 4-ohms or DVC 2-ohms, rated for at least 250 watts RMS each: 2 SVC 4-ohms, at least 250 watts RMS, or 2 DVC 2-ohms, at least 250 watts RMS Among Crutchfield’s selection of subwoofers you’ll find: You have a Memphis Audio SRX500D.1 amplifier and you want it to drive two subwoofers The amp is capable of 350 watts RMS x 1 at 4 ohms and 500 watts RMS x 1 at 2 ohms.

1000000000000 ohm
if it is ohm meter and not ohm per metre; divide by 1,000,000 to convert ohm to megaohm, then divide by 1000 further to convert metre into kilometre
The resistors are 5, 10, and 15 ohms.The current through the 5-ohm resistor is E/R = 15/5 = 3 Amp.The current through the 10-ohm resistor is E/R = 15/10 = 1.5 Amp.The current through the 15-ohm resistor is E/R = 15/15 = 1 Amp.Their total effective resistance in parallel is the reciprocal of [ (1/5) + (1/10) + (1/15) ] =the reciprocal of [ (6/30) + (3/30) + (2/30) ] = the reciprocal of [ (11/30) ] = 30/11 ohms .The total current drawn from the battery is E/R = (15)/(30/11) = (15 x 11/30) = 11/2 = 5.5 Amp.Note:The 5-ohm resistor is dissipating 45 watts.The 10-ohm resistor is dissipating 22.5 watts.The 15-ohm resistor is dissipating 15 watts.The poor battery is delivering 82.5 watts.None of this is going to last very long at all.Most likely, the battery has already expired,and/or the 5-ohm resistor has already exploded,while we've been here playing with our calculators.
Because 1 kiloohm is 1000 ohms. 1000 ohms is a higher resistance value than 10 ohms.
Yes. Inductive and capacitive reactance is measured in ohms, and it is entirely possible for reactance to be greater than 1,000, or even 1,000,000, ohms. It all depends on frequency.
Though it is tempting to say the difference is 2 ohms (8 ohms minus 2 ohms equals 6 ohms), lets look at some things. The 6 ohms is 3/4ths the resistance of the 8 ohms. If the resistances are loads, the 6 ohm load will draw 1/3rd more current than the 8 ohm load. The 8 ohm load will draw 3/4ths as much as the 6 ohm load. Those are some differences between 6 ohms and 8 ohms.
the answer is ohms
Multiply by 1000. 1K ohm = 1000 ohms
The difference between 2 ohms and 4 ohms is 2 ohms.
10 Ohms.
Yes, one mega ohm is more than one kilo ohm. Mega means million, kilo means thousand.
16 Ohms. Yes 16 ohms in series. 4 ohms in parallel
The answer is .047Megohms. 1kilo ohm is 1,000 ohms. 1mega ohm is 1,000,000 ohms. Just move the decimal over to convert.
The answer is .047Megohms. 1kilo ohm is 1,000 ohms. 1mega ohm is 1,000,000 ohms. Just move the decimal over to convert.
The correct term is 'milliohm', not 'mill ohm'. As a milliohm is one-thousandth of an ohm, 500 milliohms is 0.5 ohm.
