The resistance of the secondary wire should be from 100 to 150 ohms.
The separate resistances of two incandescent lamps are 200 ohms and 70 ohms.
What current will flow in the circuit if the external resistance is 2.5 ohms?
How far away is the break in the wire if the latter has a resistance of 80 ohms to the mile?
A pair of magnets of about 50 ohms are mounted on this support.
It is so arranged that either one or two ohms can be used at will.
It has a resistance of 5000 ohms with a mid-tap at 2500 ohms as shown at C.
The impedance of its secondary will be a quarter of this or 3,000 ohms.
Notice that I told the number of ohms and the number of volts, what are you going to tell?
If it has a million ohms we say it has a “megohm” of resistance.
unit of electrical resistance, 1867, in recognition of German physicist Georg S. Ohm (1789-1854), who determined the law of the flow of electricity. Originally proposed as ohma (1861) as a unit of voltage. Related: ohmage; ohmic; ohmeter.
ohm (ōm)
n.
Symbol Ω
A unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals.
The unit of electrical resistance, named after the nineteenth-century German physicist Georg Ohm.
