In what type of circuit will the equivalent resistance be less than the resistors in the circuit?
In a parallel circuit, the equivalent resistance is always less than the resistance of the individual resistors. This occurs because the total current can split across multiple paths, reducing the overall resistance. As more resistors are added in parallel, the equivalent resistance continues to decrease. This behavior contrasts with series circuits, where the equivalent resistance is the sum of all resistors and is always greater than any individual resistor.
What do you mean by loop resistance?
Loop resistance refers to the total resistance encountered by the current flowing in a closed circuit or loop. It encompasses the resistance from all components within that loop, including wires, resistors, and any other electrical elements. Understanding loop resistance is crucial for analyzing circuit performance, as it affects current flow, voltage drops, and overall energy efficiency. Reducing loop resistance can enhance circuit performance and minimize power loss.
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.

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.
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 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.
