It won't, hopefully. It's expected to rise from today's 7.2 billion to 11bn in the next century but to slow to a halt as birth rates fall to replacement level.

It is a situation where allele frequencies remain constant.
Equal fitness in a population
If the voltage between the ends of a series circuit changes, the current in thecircuit definitely does not remain constant. The current does change by the samefactor as the voltage.The current at every point in the series circuit is the same current.
If dc current is passed through a single coil, it is going to remain constant.
The overall growth rate of the general population is stagnant .
In common, any application if voltage is increased current will be the small amount. at the same if voltage Decreased current will be increased...AnswerAccording to Ohm's Law, 'the current flowing through a conductor is directly proportional to the applied voltage, provided certain conditions, such as temperature, remain constant'. So if you double the voltage, the resulting current will double; if you halve the voltage, the current will halve.
Since resistance is the ratio of voltage to current, we can say that halving the resistance will result in twice the current.
The number of births has to equal the number of deaths for zero population growth (ZPG). This is assuming there are no immigrations/emigrations into/out of the population.
The amount of current (amps) is controlled by the user. It's done with a variable resistor. Another thing to note is whether you are welding constant current or constant voltage. If you are welding constant current, the voltage will vary and a set Amp measure will remain constant. With constant voltage, the current will vary and that's determined by the resistance. Constant voltage should be an easier set up. I'm not 100% sure but most stick welding is constant current, which is why increasing the arc length produces more heat, because more arc length should increase the resistance, which would cause the welding machine to increase voltage to keep the current constant.
No but if you replace a constant with a function it will remain a formula
Using Ohms Law: V = I x R, where V (Voltage), I (Current), and R (Resistance). re-arranging: V/R = I Therefore if you double both the Voltage and the Resistance, the current remains unchanged.Current = Voltage / Resistance. If both resistance and voltage double the current remains the same.
