Electric current increase voltage.

Lets pretend the water flow is an electric current. A potential difference voltage across an electrical component is needed to make a current flow through it. So using a higher voltage to reduce the current can make electrical systems more efficient. This increases the pressure voltage at the end of the narrower hose pushing more water through the tank.

As the pressure incr. Let s we have a circuit below which provides 5 volts. The efficiency of electric motors also improves at higher voltages. You can think of voltage as a pushing force.

Power has been also increased. In other words the electric current flowing through a conductor increases with increase in voltage if resistance is not changed whereas the electric current flowing through a conductor decreases with increase in resistance of conductor if voltage is not changed. But there is a third factor to be considered here. This is analogous to an increase in voltage that causes an increase in current.

We can increase this circuit voltage by adding another 5 volt power source in series with this voltage. Consider a hose with flowing water for example. W a x v watts unit of power volts potential difference amps current with a lower voltage to do the same amount of work w the amps current will go up. If you don t care about the power and just simply replace the battery with a new one s with higher power rating this can increase the current when voltage increase as power is no more constant i e.

An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit. In other words current is the rate of flow of electric charge. Current is the rate at which electric charge flows past a point in a circuit. The pressure pushing the water is similar to the voltage in an electric current.

Current versus voltage comparison chart. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube which would otherwise rise to a destructive level due to the negative differential resistance of the tube s voltage current characteristic. The width of the hose. Now we re starting to see the relationship between voltage and current.

This improvement in efficiency is what drove the automobile industry to consider switching from 12 volt electrical systems to 42 volt systems in the 1990s. Now the total. If the power of the source is constant then the current would decrease when voltage increases. Now the total voltage is 10 volts.
