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.
What else can I help you with?
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
How does changing the voltage in a circuit affect the current in the circuit?
Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.
How are current, voltage, and resistance related in an electrical circuit?
In an electrical circuit, current is directly proportional to voltage and inversely proportional to resistance. This relationship is described by Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R), or I V/R.
Why current is directly proportional to voltage?
Ohm's Law: Current = Voltage times resistance, hence current is directly proportional to voltage.
What is the relationship between the keyword variable for voltage and the current in an electrical circuit?
In an electrical circuit, the keyword variable for voltage is directly related to the current. This relationship is described by Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R) in the circuit. This means that as the voltage increases, the current will also increase if the resistance remains constant. Conversely, if the voltage decreases, the current will decrease as well.
What is the relationship between resistance and voltage in an electrical circuit?
In an electrical circuit, resistance and voltage are directly related. According to Ohm's Law, voltage is equal to the product of resistance and current. This means that as resistance increases, voltage also increases, and vice versa.
What is the relationship between the current in an LC circuit and the voltage across its components?
In an LC circuit, the current and voltage are related by the equation V L(di/dt) Q/C, where V is the voltage across the components, L is the inductance, C is the capacitance, Q is the charge, and di/dt is the rate of change of current. The current in the circuit is directly proportional to the rate of change of voltage across the components.
What is the current directly proportional to?
The current is directly proportional to the voltage applied across a circuit, according to Ohm's Law (I = V/R), where I is the current, V is the voltage, and R is the resistance.
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.
What is the relationship between current and voltage in an electrical circuit?
The relationship between current and voltage in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the circuit. In simpler terms, as the voltage increases, the current flowing through the circuit also increases, assuming the resistance remains constant.
What is the relationship between voltage and current in an electrical circuit?
The relationship between voltage and current in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the circuit. This means that as the voltage increases, the current flowing through the circuit also increases, assuming the resistance remains constant.
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.
