Thanks for your contribution and thoughts but you CAN use a 4.2 volt charger for a 3 volt battery.

No. You should not use a 4.2V charger for a 3V battery. The charger is specifically designed for the battery. Attempting to use a non rated configuration, unless the charger states clearly on its label that it can handle the 4.2V battery, could result in overcharge, overheat, even fire.
Even attempting to place a resistor or zener diode in series with the battery is not a good idea, because some chargers use the voltage/time curve to sense when the battery is fully charged, and this will bias the results.
What else can I help you with?
What is the voltage of a battery that supplies a current of 42 A across 3 resistors who each have a resistance of 4 ohms?
There is insufficient information in the question to properly answer it.You need to specify if the resistors were in series or parallel.Also, it is incorrect to say "current ... across" - it must be "current ... through".Assuming that you mean a series circuit then it can be solved:R(total) = Sum of the resistors in seriesR(tot) = 3 x 4 Ohm= 12 OhmOhm's Law:V = IRV = 42 x 12= 504 Volts(Note: Because Ohm, Volt and Ampere were named after scientists they are always given capital letters. Ohm not ohm)

What is tilde operator in c and how its work?
In C, the tilde operator (~) is the bitwise NOT operator. It returns the ones-complement of its operand. That is, the individual bits of the input are inverted in the output, such that all 0s becomes 1s and all 1s become 0s. Note that the bitwise NOT (~) and logical NOT (!) operators are used for entirely different purposes. With logical NOT, the operator evaluates true (the all-ones bit pattern) when the operand is false (the all-zeroes bit pattern), which is exactly the same as the ones-complement used in bitwise NOT. However, if the operand represents anything other than the all-zeroes bit pattern, the output is the all-zeroes bit pattern. We can compare the two operators by examining what happens to the bits in each operation. Let's use the value 42 (binary 00101010) as the input. ~42 -43 !42 false Note that the binary value 11010101 represents -42 on a ones-complement system. However, most systems today use twos-complement notation for signed values, thus if we want to negate a value regardless of which notation is utilised by the system we must use the unary minus operator. On a twos-complement system, unary minus is equivalent to adding 1 to the ones-complement representation of the operand. Thus -42 is equivalent to (~42) + 1 = (~00101010) + 00000001 = 11010101 + 00000001 = 11010110 = -42.

How long to charge dead laptop battery?
Check and see how many Ah (Amper hours) your battery is. If it is for a gas/gasoline car, then it is probably around 42 Ah; batteries for diesel are usually around 72 Ah. Check the power of your battery charger. It should be something between 4-6 A. You must divide the battery capacity by the charger strength to get the time necessary. For example: your battery is 42 Ah and your charger is 6 A. Then the time needed will be 42 Ah / 6 A = 7 h. Charge your battery no longer than 7 h. Please note that overcharging the battery permanently damages it.

What size breaker is needed for a 240 volt 34 amp hot tub?
Add 25% so it comes to 42 amps
What is meant by 12V 42 AH maintenance free batteries?
24V means that the terminals of the fully charged battery will deliver a direct current of 24 volts. AH refers to the capacity of the battery (the amount of electricity it can store) - 42 AH = 42 Amp Hours Maintenance free means that there is no need/way to fill up the cells of the battery during its operational life.

Group size, 42.
How do you use four 6's to make 42?

What battery does your 1967 VW Beetle need?
The 12v model of the 1967 vw beetle is a group 42.
Why is my laptop not running on the battery i have tried an identical battery and the same it is only working on the ac it says it's charging but stuck on 42 when i pull the powercable out it dies?
Seems like the battery is not makeing a solid connection. Clean the battery connections with a pencil eraser.
What fraction would you use to find 33.3 of 42 mentally?
I would use 33.3 = approx 100/3.So 33.3*42 = approx 100/3 * 42 = 100 * 42/3 = 100 * 14 = 1400.
