To absolutely maximize solenoid current without regard for battery life, set ratio of battery time to "shorting time" so that the battery is drawn down to about 4.5 …
Learn MoreAssuming I have an inverter that can handle that startup load (about 38Ax120V=4560W), I''ll also need a battery that can supply that current short term (4560w/12v= approx 380 Amps). The deep cycle battery I have is rated at 400 cranking amps, and after the inverter losses, effects of age,etc it seems it would be only …

Learn MoreBut there''s a hitch: the battery''s range just isn''t always far enough. One option is to buy a spare battery but this comes with a hefty price tag. However, there are certain tricks that can significantly improve the range of your battery without immediately having to remortgage your house.
Learn MoreA 12vdc lead acid car battery can supply a lot more continuous current then a much smaller 12 volt battery. Small 9 volt batteries are designed to power smoke alarms for a couple of years but won''t supply 150ma for even a day.
Learn MoreIncrease the Voltage: Ohm''s Law tells you that current is proportional to voltage, so if you''re running your electromagnet on a 6-volt battery, switch to a 12-volt one. You can''t keep increasing voltage indefinitely, however, because wire resistance increases with temperature until a limiting current is achieved.
Learn MoreYou normally group them together in a serial arrangement to increase the voltage or in a parallel arrangement to increase current. The diagram shows these two arrangements. The upper diagram shows …
Learn More$begingroup$ I suspect they themselves don''t quite know what they mean by ''drawing'' current. However, a "load" is essentially a device to which power is delivered.Thus, increasing the load on, e.g, a motor, requires the motor to deliver more power and, assuming the voltage to the motor is (more or less) constant, this means an …
Learn More$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.
Learn MoreIn many devices that use batteries -- such as portable radios and flashlights -- you don''t use just one cell at a time. You normally group them together in a serial arrangement to increase the voltage or in a parallel arrangement to increase current.The diagram shows these two arrangements. The upper diagram shows a …

Learn MoreAnd this way you can remember V=RI ;) Example: Using Ohm''s Law to Calculate Current in a Circuit. The best way to learn how to use Ohm''s law is by looking at some examples. Below is a very simple circuit with a battery and a resistor. The battery is a 12-volt battery, and the resistance of the resistor is 600 Ohms.
Learn MoreThe drop depends on the type of battery and the current. If the current is above what battery is expected to provide, you can expect the battery to have lower voltage than expected, to overheat, maybe even explode. If the current provided by the battery is sufficient, the voltage drop isn''t going to be as big.

Learn MoreThe current can be found from Ohm''s Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated. The first step, then, is to find the resistance of the wire: L is the length, 1.60 m. The resistivity can be found from the table on page 535 in the textbook. The area is the cross-sectional area of the wire.
