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 you increase current by keeping voltage constant?
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
How does current affects voltage?
In common, any application if voltage is increased current will be the small amount. at the same if voltage Decreased current will be increased...AnswerAccording to Ohm's Law, 'the current flowing through a conductor is directly proportional to the applied voltage, provided certain conditions, such as temperature, remain constant'. So if you double the voltage, the resulting current will double; if you halve the voltage, the current will halve.
What happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
What will happen to the current if the resistance is decreased?
If resistance is decreased, the current will increase according to Ohm's Law. This is because current is directly proportional to voltage and inversely proportional to resistance. Lower resistance allows more current to flow for a given voltage.
Can voltage decrease when current is increased?
Yes and no. Voltage is directly proportional to current from Ohm's Law (V=IR.) Thus, when voltage increases, so does current. However, voltage can be inversely proportional to current in some situations. This can be seen in a transformer, where current and voltage are inversely proportional due to the law of conservation of energy, in which P(in) must equal P(out). Thus, a greater input voltage leads to a small output current.
Why in a circuit using power I equals Watts divided by Volts when you increase voltage the current will reduce so why does this differ from Ohms law when you increase voltage the current increases?
When you increase voltage (V) then, to get the same total power (W), the current (I) must be decreased. This result comes from the Power Law: Power = voltage x current Ohms Law does not deal with power at all, it deals only with the relationship between voltage, resistance and current: Voltage = resistance x current
What happens to the strength of an electromagnet when the voltage in the coils of the solenoid is decreased?
The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.
Why does a Led have a 470 resistor connected to the LED?
A: That resistor is there to limit the current to the LED it can be any value if the voltage is decreased or increased or no resistor if the voltage across the led is equal to the forward voltage drop.
The voltage drop in line can be decreased by?
The voltage drop in a line can be decreased by
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.
What is the reason why it is better to use high voltage instead of low voltage on long distance?
High voltage reduces the amount of energy lost due to the resistance of the transmission material (conductor), by reducing the current. In other words, increasing voltage reduces current, and lower current means less resistance loss. Voltage and current have an inverse relationship, and later on when the electricity gets closer to the consumer, voltages can be decreased which increases the current. Increased current means higher resistance, and it is resistance that does the work.
