Ohm
I think it is due to the resistance to the electrical appliance, the resistance offered by the electrical appliance works as a load in the circuit and when load is removed it causes sparking.
any device that converts energy from one form to another usually electrical to mechanical by using the property of all electrical non-conductors, or dielectrics, that causes them to change their shape under the application of an electric field
Resistors are measured in units of Ohms (Ω).
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
The property of a substance enabling it to slow down electricity is called resistance and is measured in ohms. This ability is called electrical resistance. Every substance has this. Gold has the minimum resistance for electricity. Such substance is called electrical conductor. And there are substance where the electrical resistance is affected by heat, light and other conditions. And for those substance where electricity can not flow are called electrical insulators (non-conductors) such as wood and ceramics.
They are both good electrical conductors which is unusual as non-metals are normally not very good electrical conductors.
This property was not measured on francium.

No, gold is not the best conductor. At room temperature, silver is a slightly better conductor. The best electrical conductors are the so-called superconductors, which are materials that only exhibit the property of superconductivity at very low (cryogenic) temperatures. When exhibiting the property of superconductivity, they have a resistance of zero.
No. Resistivity is a material property, and is defined as the resistance for a piece of material of some standard size.
electrical resistance
hardness
Anything with the property of zero electrical resistance is called a super-conductor.
When the circuit needs the electrical property of resistance, of course.
Capacitance.
