Ways to reduce electrical resistance: increase the diameter of the conductor, decrease or increase the temperature of conductor (depending on its thermal characteristics), decrease the length of the conductor. A change in the material out of which the conductor is made can decrease resistance, too. And there is the phenomenon of superconductivity.
In a simple circuit the resistance can be lowered by adding resistors in parallel. The total circuit resistance will then decrease. You can also reduce resistance by substituting resistors of lower value, or by adjusting a potentiometer, or pot, to a lower value.

What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
Who when and how was electrical resistance discovered?
electrical resistance was discovered by Georg Ohm in the late 1820's.
What is the name of an instrument used to vary electrical resistance?
Rheostat is the name of an instrument used to vary electrical resistance.
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
Why is electrical resistivity important to a design engineer?
electrical resistance increases current flow decreases.so to know the current flow in the network ,electrical resistance is required.AnswerResistivity is important, because it is one of the three factors that affect the resistance of a material. The other factors are the length and cross-sectional area of the material.
What effect does it have on the voltage drop in an electrical cable if the resistance of the cable is decreased?
It will decrease the voltage drop.
What happens to resistant if wire diameter is decreased?
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.
What happens to the power of an electric circuit of the resistance is decreased?
if the resistance is decreased and the current stays the same, then the power decreases.
Do extension cords reduce power when used for electrical appliances?
Yes, extension cords can reduce power when used for electrical appliances due to resistance in the cord, which can lead to voltage drop and decreased power delivery to the appliance.

What are the units of resistance in an electrical circuit measured in?
The units of resistance in an electrical circuit are measured in ohms ().
What are some of the ways energy is lost in machines?
Energy can be lost in machines through friction between moving parts, air resistance, electrical resistance in wires, and heat dissipation. These losses result in decreased efficiency and can lead to wasted energy in the form of heat.
What is resistance expressed in?
Electrical resistance is measured in Ohms.
How does electrical resistance cause energy to be wasted?
Electrical resistance causes energy to be wasted by generating heat as current flows through a conductor. This heat dissipates into the surroundings instead of being used for useful work, leading to energy loss in the form of heat. This inefficiency results in decreased energy efficiency and higher electricity consumption.
What component in an electrical circuit provides resistance?
The component in an electrical circuit that provides resistance is called a resistor.
What is the opposition to the flow of electrons is called?
Resistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistance
