Understanding what causes global poverty is a crucial part of the process of devising and implementing effective solutions. Most analysts would agree that there is no single root cause of all poverty everywhere throughout human history.However, even taking into account the individual histories and circumstances of particular countries and regions, there are significant trends in the causes of global poverty. Discrimination and social inequality. 2  Poverty and inequality are two different things, but inequality can feed widespread poverty by barring groups with lower social status from accessing the tools and resources to support themselves.
Alternately, if the resistance in a circuit is increased and the voltage does not change, the current will decrease. The second version of the formula tells us that the voltage can be calculated if the current and the resistance in a circuit are known. It can be seen from the equation that if either the current or the resistance is increased in the circuit (while the other is unchanged), the voltage will also have to increase. The third version of the formula tells us that we can calculate the resistance in a circuit if the voltage and current are known. If the current is held constant, an increase in voltage will result in an increase in resistance.
The total resistance affects the total current. Each individual resistor only gets a piece of the current. Voltage remains the same, so the circuit as a whole, with the total current, must have a lower resistance than the individual loops (with their lower, partial currents).
