Your question reveals fundamental misunderstandings about the nature of electricity.
'Voltage' is simply another word for 'potential difference', and a potential difference appears across opposite ends of the resistor; it doesn't 'travel through' that resistor! Current, on the other hand, DOES 'travel through' the resistor and is caused by the potential difference across the resistor.
Resistance is the ratio of potential difference to current. So if the resistance remians unchanged when the current through it doubles, then it has happened because the potential difference has doubled.

This means that if you increase the current through a resistor, the voltage drop across the resistor must also increase.

What happens to current in a parellel circuit if a resistor load increases?
Your question needs rephrasing; as it stands, it makes no sense.
What happens to the resistor when there are more components?
Nothing happens to the resistor other than it may interact with the other components so as to perform a desired function.
What happens to the total impedance of a series RC ciRCuit as the frequency is increased?
when the frequency is increased the total impedance of a series RC circuit is decrease.
What happens if you remove emitter resistor in RCcoupled amplifier?
what happens if we remove Rc in RC coupled amplifier
What happens to the voltage if the current increases?
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.
When a resistor is connected in parallel what happens to the size of current form the battery?
When a resistor is added the current goes down, that is expressed in the equation current= voltage/ resistance
What happens to the reading on an ammeter if the value of a variable resistor is increased?
it explodes and burns everyone in the room.
What happens to the current flowing through a metal resistor when the voltage across is increased?
When the voltage is increased across a metal film resistor, the current flow will also increase. Ohm's law states that the current flowing through a resistor is directly proportional to the voltage across that resistor. I = V/R Let us assume an initial voltage drop across a 4.99K ohm metal film resistor is 5V. The current flow through the resistor is calculated to be: I = 5/4990 = 0.001 Amps or 1 mA If that voltage were to say double to 10V: I = 10/4990 = 0.002 Amps or 2 mA Using these values it is also possible to calculate the power dissipated by the resistor. P = I*V = 0.002 * 10 = 0.02 Watts This power calculation determines the minimum physical case size needed for the resistor to function within these conditions. Anything smaller, the resistor will fail.
What happens to the current in the circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens when more than one resistor is connected to a circuit?
the current flowing in will be low
What happens to the current in a circuit if a 10 ohm resistor is removed and replaced by a 20 ohm resistor?
Voltage, current, and resistance can be related by this formula. V = iR, where I is the current. Assuming that the voltage stays constant, current will decrease. Hope this helps!
What happens when a switch in a current is opened?
current through the switch become 0.and switch become a high value resistor.
What happens when a switch a current is opened?
current through the switch become 0.and switch become a high value resistor.
What happens to the ammeter reading if resistor is removed?
Opening any circuit will stop the current from flowing.
What slows down current and converts electrical energy into other forms of energy?
That sounds like a resistor. However, please note that "slow down a current" is not a very accurate description of what happens. What the resistor does is take energy away from the current.
When the resistance in a circuit is increased what happens to the current?
The flow of electrons meets an increased impedance to it's flow.
What happens to the current in a circuit when the resistance is increased?
The flow of electrons meets an increased impedance to it's flow.
