What does it mean to say that current and voltage in a circuit are directly related?

It means that when one increases, the other increases as well. Also, it implies that this increase is proportional - if the voltage is doubled, the current will also double.
Note 1: Normally, the voltage is considered the independent quantity; that's the quantity you can control directly. And if the voltage changes, so will the current.
Note 2: In simple circuits, such as those that only have a voltage source and resistors, the relation will be a direct proportion. With electronic components, such as a transistor, the relationships can be more complicated.

In the electrical circuit the higher the voltage the lower the?
Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
If voltage changes in a ac circuit what happens to current?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
If the decrease voltage and the resistance stays the same is current increased or decreased?
This question follows Ohm's law which states, "Current is directly proportional to the applied EMF (voltage) and inversely proportional to the current in the circuit. <<>> decreased
Why current is directly proportional to voltage?
Ohm's Law: Current = Voltage times resistance, hence current is directly proportional to voltage.
How are current and voltage related are they directly proprtional or inversely proportional?
Current and Voltage are directly proportional. V=voltage, I=current, R=resistance V=I*R
How do voltage and current and restistance all link together?
According to ohm's law, voltage in a circuit is directly proportional to current in the circuit and when that proportionality sign is taken off to equals to, a constant is introduced with current and is called resistance. Therefore Voltage in a circuit equals to product of current and resistance in that circuit.
If you know the current through one resistor in a DC circuit then do you know the current through all the other resistors?
No. Current and voltage are directly proportional to one-another and both are related to resistance by Ohm's law: V = IR or Volts = Current * Resistance So the current will depend upon the voltage and the circuit resistance by rearranging the above equations: I = V/R Meaning that the current will decrease as circuit resistance is increased if the voltage remains constant.
What is the definition of 'volts'?
Volts are the measure of electrical force or pressure that causes current to flow in a circuit. This is related directly to electricity. Voltage is also measured in volts.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
In the electrical circuit the higher the voltage the lower the?
Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
How can in series connection current remain constant while the voltage change while by ohm's law voltage is directly proportional to current?
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.
How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
If voltage changes in a ac circuit what happens to current?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
How does the potential difference across the electric circuit affect current?
In a very simple way. As long as nothing changes in the circuit, the current that flows from the power supply or battery into the circuit is directly proportional to the voltage of the supply. -- If you double the voltage across the ends of the circuit, the current will double. -- If you turn the voltage up to 3.4027 times its original value, the current will increase to 3.4027 times its original value. -- If you decrease the voltage by 81.7 percent, the current will decrease by 81.7 percent.
