- A parallel circuit is a circuit with
- more than one path for an electric current.
- A series circuit is a circuit with
- only one path for an electric current.
- An electromagnet is an arrangement of
- wire wrapped around a core or wire.
- A circuit is a path
- made for an electric current.
- An electric field is the
- space around an object where electric forces occur.
- A charge is the measurement of an
- of an object extra positive or negative particles.
- A magnetic field is the
- space around a magnet where the force of the magnet acts.
- A resistor is the material -------- but does not stop the flow of electric current.
- resists.
- Static Electricity is the charge that
- stays on an object.
- An isulator is the material that
- an electric current can't easily pass through.
- A conductor is the material that
- an electric current can pass through easily.
- Magnet poles
- Are the ends of the magnet.
- A magnet is an object that
- attracts things made of iron and steel.
- An electric cell supplies ------ to move chargees through a circuit
- energy
- An electric current is
- the flow of elctric charges.
- A circuit with three bulbs and one battery in a circle is a
- series circuit.
- If a bulb burns out in a series circuit, then
- no other bulbs will light.
- One good way NOT to control an electromagnet is
- to heat or cool it.
- Magnets attract to each other
- at opposite poles.
- Copper wire in a circuit conducts
- elctricity.
- When two objects both have positive charges they
- repel each other.
- Electromagnets in motors are used to cause
- motion.
- A bar magnets pull is strongest at
- both poles.
- An object hads a negative charge if it has more -------particals than positive charges.
- negative
