2) What must be connected for an electrical current to flow in a simple current?

d.moving magnets,conductors, load to do work

here moving magnets will work as generator and conductors is used as connectors.

5)What is the purpose of a load in a circuit?

c.provide resistance to keep the voltage strong

Load will provide the resistance to the circuit and help to build the voltage across it

6) What cause an electric current from a generator

d.Magnets and conducting wires move near each other

here when magnets move near wires then it will induce the electric current and behaves like generators

7) What do all generators have in common

b.they transform mechanical into electrical energy

They have magnets and rotating coils which will convert magnetic energy to electrical energy

8) How can we measure electrical current

b.the pressure force is voltage;the # of electrons moving is amperes

this voltage and number of electrons will help to calculate current
