If the resistance of the variable resistor increases, the current flowing through the circuit decreases. As a result, the bulb will emit less light or may not light up at all, depending on the magnitude of the resistance increase.
If the resistor is removed from the circuit, the total resistance in the circuit decreases. This causes the total current in the circuit to increase, which would result in an increase in the ammeter reading.
In a series circuit, if one resistor is replaced with a resistor of lower resistance, the total resistance in the circuit decreases. This leads to an increase in the overall current flowing through the circuit.
When a common ohmic resistor is heated, its resistance typically increases.
An idea about what happens to one variable when a second variable changes is called correlation. Correlation measures the strength and direction of the relationship between two variables. It can help us understand how changes in one variable may be associated with changes in another variable.
If the wire diameter is decreased, the resistance of the wire will increase. This is because with a smaller diameter, there is less cross-sectional area for the electrical current to flow through, causing more hindrance and resulting in higher resistance.
it explodes and burns everyone in the room.
A unit increase in the x-variable is associated with a greater increase in the y-variable.
If you add a second resistor, the resistance of series circuit will increase.
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.
If the resistor is removed from the circuit, the total resistance in the circuit decreases. This causes the total current in the circuit to increase, which would result in an increase in the ammeter reading.
The contribution ratio is the relationship between total sales revenue and total variable costs. If the components change, such as an increase in sales revenue or a decrease in variable costs, the contribution ratio will increase. Conversely, if sales revenue decreases or variable costs increase, the contribution ratio will decrease.
In a series circuit, if one resistor is replaced with a resistor of lower resistance, the total resistance in the circuit decreases. This leads to an increase in the overall current flowing through the circuit.
The dependent variable.
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

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.
