It causes the electricity flow faster,which in term increases the electrical flow.
CommentChanging a circuit's resistance doesn't cause 'electricity' to flow faster -or slower, come to that! First of all, 'electricity' isn't a quantity, so it cannot be measured, and it doesn't flow! If, by 'electricity', you mean 'current', well that isn't made to 'flow faster' either.
If the supply voltage is constant, then increasing a circuit's resistance causes the magnitude of current to fall. This has nothing to do with its 'speed'!
What else can I help you with?
What happens to the resistor when there are more components?
Adding more components changes how a resistor works. In a series circuit, resistance goes up, slowing current. In a parallel circuit, resistance drops, letting more current flow. The effect depends on how the components are connected.
What is electricity current potential difference and resistance?
Voltage is the electrical pressure in a circuitAmperes (amps) are the measure of electrical current in a circuitOhms are the measurements of resistance in a circuitCurrent is essentially how fast electrons are moving in a circuitResistance is what impedes the electrical current, and can be found in the wire or various loads in a circuitHope this helps!
What is the relationship between current and resistance?
They are proportional to each other with a constant of 1/V, by rearrangment of the formula V = IR.
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.
What do you mean by 'cold resistance' and 'hot resistance'?
Metals that make up typical resistors (and many other electrical components for that matter) tend to heat up as current flows through them. "COLD" resistance is the resistance before it is operating and "HOT" resistance is the resistance after some operating time has elapsed.
If resistance goes up how is current affected?
If resistance goes up in a circuit, the current will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, meaning that as resistance increases, current decreases.
As resistance goes up where do current goes?
down
What happens when total resistance goes up?
In that case, it is more difficult for charge to flow; the total current will decrease.
How does resistance effect the flow of current in a wire?
Resistance in a wire causes a decrease in the flow of current. This is because resistance impedes the movement of charge carriers through the wire, leading to a reduction in the overall current. Ohm's Law (V = I x R) shows the relationship between voltage, current, and resistance in a circuit.
Explain how changing the resistance in a circuit chages the current?
Ohms' law says if voltage stays constant resistance controls the current flow. Resistance goes up, current goes down. E/I*R.
If resistance goes up does current go down?
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
What happens to the total resistance of a series circuit when another resistor is added?
Simply put, the purpose of a resistor is to 'resist' the flow of current. Ohm's Law tells us that for a given voltage, the larger the resistance, or value of that resistor, the lower the current that will flow. Ohm's Law states that I (current) = E (voltage) / R (resistance) - where current is measured in amps, voltage is measured in volts and resistance is measured in ohms.
Why does the skin resistance go down and the current goes up when you lie to a lie detector?
because you sweat.
Why it is said to be negative resistance region?
A negative resistance region is where the current goes up while the voltage goes down, or vice versa. This is a characteristic of the esaki or tunnel diode, when it is in its tunnel region.
What happens to the resistor when there are more components?
Adding more components changes how a resistor works. In a series circuit, resistance goes up, slowing current. In a parallel circuit, resistance drops, letting more current flow. The effect depends on how the components are connected.
What happens to electrical resistance of most conductors when heated?
Resistance goes up creating more heat which eventually leads to an open circuit.
What is the effect of the temperature on the resistance?
It varies. On some items resistance goes up, some it goes down when temperature goes up.
