What happens to the current through a component as the voltage increases?

In any conductor, increased current flow will result in voltage drop. This won't have any effect until you reach about 5% of the circuit voltage, at which point your efficiency declines. If the increased current trips the breaker, then your Voltage will be 0
For reference: Vd= (1.732 x K x I x L) / cmil
Vd is Voltage drop in Volts
1.732 is sq rt of 3 for three phase circuits. For two phase or single phase circuits use 2
K is resistance in Ohms of 1cmil, 1ft of conductor.
K=12.9 for copper conductors, 21.2 for aluminum, both at 75 deg C
I is the current (hence, the more current, the more voltage drop)
L is the length of the conductor
cmil is the wire size, or more accurately, cross-sectional area of the conductor

What happens to the resistance of the bulb as the current passing through it increases?
Yes but very slightly,because temperature coefficient of bulb element is very low.
What happens to the energy in a circuit when the current passes through a component?
A: If there is resistance within the device it will cause to dissipate some of the energy as heat. The rest will continue
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.
Current travels from a power plant to a transformer that increases voltage through a what?
circuit
Does a Cpacitor allow ac to pass through it?
no capacitor does not allow ac component .if allow then inductor allow dc component .
What is the component that allows current to pass through easily?
A Conductor
What happens to the resistance of the bulb as the current passing through it increases?
Yes but very slightly,because temperature coefficient of bulb element is very low.
What happens if the temperature of a diode increases?
When the amount of current passing through a circuit increases, it generally increases the temperature, and consequently the resistance. Simply stated, it is harder for the current to pass through the circuit if the temperature increases. The Large Hadron Collider uses superconductors to pass current to its electromagnets. A superconductor passes current through its circuit materials with almost no resistance at all, generally by supercooling the circuit materials.

Should an ammeter always be connected in parallel with a component?
No, an ammeter should never be placed in parallel with a component - it should always be placed in series, so that the current through the component is measured.If you place an ammeter in parallel with a component, you create a short circuit around the component. Depending on the rest of the circuit, you could damage the circuit, damage the ammeter, create a fire, etc. You certainly will affect the current through the component, and that is not what you want to accomplish.
What happens to an iron nail if you pass electricity through it?
The temperature of the nail increases.
Consider two identical resistors wired in series one behind the other If there is an electric current through the combination the current in the second resistor is?
Two resistors wired in series (no mater if they have the same resistor value or not) will always have the same amount of current flowing through them. Therefore, the current flowing through the second resistor will be equal to the current flowing through the first one. The current through every component in a series circuit is the same. The voltage across every component in a parallel circuit is the same.
Does a Cpacitor allow ac to pass through it?
no capacitor does not allow ac component .if allow then inductor allow dc component .
What is resistor and its use and working?
resistor is a passive component which opposes the current flowing through a closed ckt. use in opposition of current in ckt .
What component included in a circuit and is designed to prevent too much current from flowing through the circuit?
A fuse.
