Why does the current immediately increase in current after reaching a certain voltage rather than a gradual current increase?
It depends on the nature of the circuit. In a purely-resistive circuit, the current would rise immediately because resistance merely limits its value, it doesn't oppose any change in current. But in a resistive-inductive circuit, for example, the inductive component opposes any change in current, so the current will rise more gradually.
What else can I help you with?
If the resistance increases what will happen to voltage and current?
If you have a simple circuit. For eg: One voltage source and one resistor, then the voltage of the circuit will always remain the same, the current however will decrease following Ohms' Law V=I*R. If we have a current source instead of a voltage source, we are forcing the current to be a certain value so if we increase the resistor value the current will remain the same but the voltage will increase.
What is the cutting voltage of a silicon diode?
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.
When did the delivery of current expected to increase during defibrillation?
delivered current during defibrillation is expected to increase with which of the following?
What device can be used to increase current in a DC circuit?
Transformer or instrument transformer. It can increase and decrease current output.
When resitance increases current does what?
Current goes down with an increase in resistance.
How do you increase voltage in a generator?
At least to a certain extent, by increasing the field current. Or In Real Power Plant they decrease the power factor to increase the voltage.
Why does OCC curve become flat after certain field current?
The OCC (Open Circuit Characteristic) curve becomes flat after a certain field current because the magnetic saturation of the field winding is reached. At this point, increasing the field current does not result in a proportional increase in the generator's terminal voltage. The core material of the generator becomes saturated and can't further increase the magnetic flux.
How do you increase current in a battery?
we can increase the current in battery by using current amplifiers or chopper's s the easy way to increase the current in battery........
Will a capacitor increase amps?
A capacitor does not increase amps; instead, it stores and releases electrical energy. In an AC circuit, capacitors can influence the current flow by affecting the phase relationship between voltage and current, which can lead to higher apparent current (amps) in certain conditions. However, they do not increase the actual current supplied by a power source. The overall current still depends on the power supply and the load connected to the circuit.
An increase in ocean salinity can increase what creating a current?
An increase in ocean salinity can increase density creating a convection current.
What effect does heat have on electric current flow?
Increasing heat can increase the resistance of the material through which the current flows, which can reduce the flow of electric current. However, in some cases, heat can also increase the kinetic energy of charge carriers, leading to increased current flow in certain materials like semiconductors.
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
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.
When resistance increase the current does what?
The current decreases.
Does lowering resistance increase current?
Current is proportionally inverse to resistance and when the voltage is fixed, lowering resistance will increase the current
What is negative resistance region?
Negative resistance region refers to a region on a current-voltage characteristic curve where an increase in voltage leads to a decrease in current. This phenomenon is opposite to what is expected in regular resistors, where an increase in voltage typically results in an increase in current. Negative resistance can be created in certain electronic components, such as tunnel diodes, and is used in various electronic applications like oscillators and amplifiers.
If the resistance increases what will happen to voltage and current?
If you have a simple circuit. For eg: One voltage source and one resistor, then the voltage of the circuit will always remain the same, the current however will decrease following Ohms' Law V=I*R. If we have a current source instead of a voltage source, we are forcing the current to be a certain value so if we increase the resistor value the current will remain the same but the voltage will increase.
