Sugar is not used in electrical circuits.
The filament in an incandescent light bulb resists the flow of electricity. Copper wire has relatively low electrical resistance, making it a common choice for transmitting electricity. Insulators, such as rubber or plastic, have high electrical resistance, which prevents the flow of electricity.
Thermal resistance: diamond Electrical resistance: copper Optical resistance: quartz

R= ΟL/A Ο- electrical resistivity of the materialL- length of the conductor.A- cross sectional area of the conductor.
an ohm meter OR multimeter is used to measure the electrical resistance...
Voltage(volts)=Power(watts)/Current (ampheres) Or Voltage=Curren X Resistance(Ohms) -X
Voltage(E)=Amps(I) x Resistance(R) (ohms) use this formula to solve for other two.
electrical resistance was discovered by Georg Ohm in the late 1820's.
Electrical resistance is measured in Ohms.

In the formula E=IR, E represents voltage (in volts), I represents current (in amperes), and R represents resistance (in ohms). This formula is known as Ohm's Law in electrical engineering.
High resistance means insulation
Rheostat is the name of an instrument used to vary electrical resistance.
