The most common applications for series circuits is in Christmas tree lights and putting a fuse in series with delicate electronic equipment.
Each component in a circuit causes a voltage drop. Therefore, the series circuit should only be used where the voltage drop does not interfere with the proper functioning of the components in the circuit.
On the other hand, where all of the compenents in a circuit require the same supply voltage, then a parelell circuit should be used.
Answer: because the circuit you have quoted is a parrallel type, thevoltage will be the same across all the components/ resistors inparallel . -- 78 volts. however i wonder if you needed to calcualte the current flow
Answer: No. In a 2.4 Volt battery there is more "Juice" for the battery to last longer and perform better. Also a 2.4 battery is capable of powering things that are a bit more advanced and sophisticated.
Answer: Diodes only allow the current to travel in one direction, they are often used to prevent current leakage from one point to another, "basically the current can back up and go into other parts of the circuit without the diode. If a Diode is placed in Series with a circuit it will only allow the current to flow in one direction. For instance in Power supplies that convert AC electricity to DC they use a special diode Called a bridge Rectifier, Basically it used 4 Diodes in series to smooth out and condition the power so that when it comes out it is only Positive and Negative Diodes are also Half wave, meaning that only half of an AC cycle will come out the result is an Oscillating DC. So when a Diode is in Parallel with a component it is either Bypassing that component in one direction or it is disallowing the current to flow Backward on the component..
Answer: In a parallel circuit, the same (supply) voltage will appear across each branch. So, in your example, 12 V will appear across each of the 24-ohm resistors. To find the current through each resistor, then, you simply divide the supply voltage by the value of that resistor.
Since the supply current is the sum of the two branch currents, to find the supply current, you simply add together the currents passing through each resistor.
Answer: Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms.
The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.
Answer: Yes there should be an in-line fuse. If there is not an in-linefuse and there is a voltage spike in the vehicle the fuse will popand disable the circuit where as if there was no fuse the accessoryor mechanism could be destroyed.
As above suggests, the fuse must be put in series. If it is inparallel, the fuse should blow immediately on completing thecircuit, because it is effectively a short, which will cause largecurrent flow into the fuse until it blows. Never, never, never puta fuse in parallel with whatever you want to protect - that defeatsthe point of the fuse.
Answer: The main reason why is that it would be very deceptive toconsumers. For example. a 120v circuit that draws one amp; might beable to be converted to 240v that would only draw 1/2 amp. At 480v,that same circuit would only draw 1/4 amp, so you would need to beable to figure out what amperage you need at 480v. Now there isalso more to understand with this. A 480v ac system consists ofthree phases, the most common is 3 phases of 277v. If you measuredone phase to ground you would read 277, if you measured phase tophase, you would read 480v. There are also other varaitionsincluding 240v to ground and 480 phase to phase. Depending on thetap off of the transformer you might actually be able to use a 250vfuse on each phase. Since each phase is fused separately, I canguarantee you will never find one that reads 480v to ground. Ifnone of this makes sense, than you should go to the store andpurchase the 480v fuse, or call an electrician. Fuses have a small connecting link in them that melts in responseto the current. Ratings below 32 volts can use almost any type ofmetal link in air, and it will safely interrupt the circuit. As thevoltage rating goes higher, special exotic properties of metals andfiller materials have to be used to safely stop the current. If thefuses does not have the correct properties to stop the current arc,the fuse can explode or become a conductor feeding a short circuit!This could cause switchboard failure or personnal inuries.
Answer: yes Yes you can, but I would use a charger that has an amp switch, so you can use the lowest amperage there is on the charger...like 2 amps at the most, mine has a 10/2 switch on the charger..I would only use 10 amp for a VERY short time, and if you can keep an eye on it, then switch it to 2 amps...most motorcycle batteries can be done this way..
Answer: #6 copper wire has a resistance of 0.3951 ohms per 1000 ft (fromwire tables). A 750 ft circuit contains 1500 ft of wire so theresistance is 0.5926 ohms. With 65 amps flowing the voltage drop is38.5 volts. The power lost in the cable is 2½ kW.
