If voltage and current are proportional why do they increase voltage in powerlines in order to decrease current?
Low current will equal low power losses due to the resistance of the cable. I squared R. (I is transmission current and R is resistance/Metre of cable) by increasing the voltage for the same amount of power the current decreases. Power transmission will take that advantage to transfer less current for the same amount of power.

Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Current is proportional to the potential difference and inversely proportional to its?
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
Why secondary terminal voltage decreases with increase in load?
An increase in load (equivalent to a decrease in resistance*) causes an increase in load current. This increases the internal voltage drop within the transformer, and the terminal voltage reduces accordingly.[*An increase in load means more current is being drawn by that load, so an increase in load is equivalent to a decrease in load resistance]
If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
What will cause an increase in current flow in a simple series circuit?
An increase in voltage or a decrease in resistance will cause an increase in current flow in a simple series circuit. This is because current is directly proportional to voltage and inversely proportional to resistance according to Ohm's Law.
Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
Why does collector current increase with base current?
the collector current is directly proportional to the base current
What does an increase in voltage cause in an electric circuit?
It causes a proportional increase in current.
Does a change in current assets increase or decrease cash flow?
It depends on the current asset, so the change of current asset might be increase or decrease cash flows.
How does current change through a resistor?
When an electric current flows through a resistor, the resistor resists the flow of the current, causing a decrease in the current. This decrease in current is proportional to the resistance of the resistor, as described by Ohm's Law.
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
Since the current recession has there been an increase or decrease in bankruptcy?
Increase.
Issuance of short term bond increase or decrease current ratio?
decrease
What does Ohm's law describe about the relationship between voltage, current, and resistance?
Ohm's law describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. This means that if the voltage increases, the current will also increase, but if the resistance increases, the current will decrease.
