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 when the value of a slope gets bigger?

A unit increase in the x-variable is associated with a greater increase in the y-variable.


What happens in a series circuit if the resistance is halved?

If you add a second resistor, the resistance of series circuit will increase.


What happens to voltage when resistance is increased?

Ohms law is V=I X R. If resistance (R) is reduced and current (I) is constant, then voltage (V) must decrease. You can see from the equation that they are proportional to one another. If, however, R is reduced and V is held constant, then I must increase (I and R are inversely proportional). The only way V can increase is if either or both I and R increase.


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.


How does a volume knob work or what happens to make the sound increase when the knob is turned?

They key to volume control is a variable resistor. A variable resistor uses a resistance track with connections at both ends. There is wiper that moves along the track as the volume knob is turned. The tracks are usually rotary for volume knobs, or tracks for volume sliders. The variable resistor may be used as a rheostat, which means that only two terminals are used (the wiper and one end of the track). By turning the knob, the wiper sweeps across the track, which will effectively vary the resistance from 0 to maximum. A rheostat is usually used to vary current so they would be useful for varying the brightness of a lamp. A variable resistor can also be used as a potentiometer, which uses all three connections (both ends of track and wiper). If you connect the track terminals across a power supply, then the wiper terminal is used to provide a voltage, which can be varied from 0 to the maximum (the supply voltage). Potentiometers are usually used for amplifiers. Hope this helps

When the current traveling through a resistor is increased what happens to the voltage that travels through the same resistor?

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.


What happens to the voltage values of other resistors when a short occurs in one of them?

If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.


What happens when resistance is varied in a circuit?

A resistor will not change its value, unless the voltage exceeds the designed power capacity of the resistor. As the voltage increases, the current will increase, if the current gets too high it will cause the temperature of the resistor to increase, if the temperature exceeds the power rating of the resistor then the resistance WILL change. If it goes too High in temperature the resistor will open and current will no longer flow. A resistor is used to control current, and indirectly the .voltage depending on the application. Hope This helps. You must use Ohms Law to see the relationship.


What is the difference of a dependent variable and an independent variable?

An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,
