What is a resistor in electricity?
Resistor is an eletrical and electronical part whose function is to decrease the value of the voltage in a circuit, consequently reducing the value of the current, which is measured in Amperes.
Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
What effect does reducing resistance have on the power in a circuit?
Since power = voltage2/resistance, reducing the resistance will increase the power of the circuit. Incidentally, power is not 'consumed'; it's energy that's consumed.
How do we decrease the brightness of a bulb?
If the bulb is of the incandescent variety, then reducing the current in the circuit will do this.
Why initially capacitor taking more current?
Consider the instantaneous DC analysis. Initially, the capacitor has zero resistance. You apply a voltage and current is controlled by other resistive elements alone. As the capacitor charges, its effective resistance rises. This adds to the net resistance in the circuit, reducing current. At full charge, the capacitor has infinite resistance, so there is no current. Remember that the equation for a capacitor is dv/dt = i/c.
What medications decrease venous return reducing peripheral vascular resistance?
Vasodilators
How does the concept of parallel resistors connected to the same voltage source affect the overall resistance in a circuit?
When resistors are connected in parallel to the same voltage source, the overall resistance in the circuit decreases. This is because the current has multiple paths to flow through, reducing the total resistance that the current encounters.
There are two light bulbs in a circuit wired in parallel a third bulb is added what is the effect on tolal resistance of adding the third bulb?
Adding any additional element in parallel will reduce the combined resistance. Do some sample calculations to get a "feel" for this: Total resistance (R) is calculated as 1/R = 1/R1 + 1/R2 + 1/R3... In other words, take the reciprocal of the individual resistances, add them, and then take the reciprocal of the result.
When tempratere increase resistance increase and when resistance increase current decrease why?
That's what "resistance" is all about: reducing the current for a given voltage. In fact, you can DEFINE resistance as voltage divided by current.
How can air resistance be decreased?
Air resistance can be decreased by making the object more aerodynamic, such as by reducing its size or shaping it to minimize drag. Smooth surfaces and streamlined designs help to reduce turbulence and resistance. Additionally, reducing the object's speed can also decrease air resistance.
How does the resistors work in a integrated circuit?
A resistor implements electrical resistance as a circuit element. It works in an integrated circuit by reducing current flow, and to lower voltage levels within circuits.
Do slippery things increase or decrease friction?
Slippery things, such as water or oil, typically decrease friction by reducing the contact between surfaces. This creates a lubricating effect that reduces the resistance between the surfaces.
How can you decrease the degree of damping?
You can decrease the degree of damping by reducing the amount of friction or resistance in the system. This can be achieved by using lighter weight damping materials, adjusting the damping coefficients, or using a less viscous damping fluid.
What is the percentage amount of 5 from 65?
Reducing from 65 to 5 is a 92.3077% decrease. Reducing from 65 to 60 is a 7.69231% decrease.
Which forces cause a decrease in acceleration?
Friction and air resistance are two common forces that can cause a decrease in acceleration. Friction between surfaces can oppose motion, while air resistance acts against objects moving through the air, both reducing the net force acting on an object and therefore its acceleration.
What is a resistor in electricity?
Resistor is an eletrical and electronical part whose function is to decrease the value of the voltage in a circuit, consequently reducing the value of the current, which is measured in Amperes.
How could you reduce air resistance?
You can reduce air resistance by changing the shape of the object to be more streamlined, decreasing the surface area exposed to the air, and using smooth surfaces to minimize turbulence. Additionally, reducing the speed at which the object moves through the air can also help decrease air resistance.
