Question

define the fallowing terms a) d.c motor b ) transformer c) capacitor d) frictional electricity

Answer 1

a) A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy

b) A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

c) A capacitor is a passive two-terminal electrical component that stores potential energy in an electric field. The effect of a capacitor is known as capacitance.

d) Frictional Electricity is the electricity produced by rubbing two suitable bodies and transfer of electrons from one body to other.

Answer 2

dc motor is a motor which is used for making toys and projects this is on with electricity inside the DC motor have the copper wire and the magnets
anything that transform from its original state to another it's called transformer or the object that supply the electricity to the object it is made up of copper wire
capacitor is used for maintain the value of electricity are you say the capacity of of electricity
