A spherical surface curving toward the object or image in front of it (depending on which way the component is facing).
What is concave?
Three fields
What are gravitational, magnetic, and electric?
Stationary accumulation of charged particles.
What is static electricity?
DC means
What is direct current?
Electrical pressure that forces charge to flow.
What is voltage?
A spherical surface curving away from the object or image.
What is convex?
This causes a gravitational field.
What is mass?
Two types of charged particles.
AC means
What is alternating current?
A device that regulates electric current.
What is a resistor?
This can be seen and projected onto a screen.
What is a real image?

What is an electric field?
The pump in a water circuit is equivalent to what in an electrical circuit.
Static electric forms by
What are friction, conduction, and induction?
When the presence of nearby charges causes movable charges in a metal to accumulate.
What is induction?
CCD stands for
What is a charge-coupled device?
This lowers AC voltage while also lowering or raising the current.
What is a transformer?

The strength of the induced current is proportional to the number of turns in the coil and to the rate at which the flux through the coil is increasing or decreasing.
What is Faraday's law?
The pipe is equivalent to
What is a wire?
Electrons flow easily
What are metals?
A machine that uses an engine to rotate a coil of wire in a magnetic field, producing electric current.
