Hydropower output depends on two things: how much water moves and how far it drops. Volume and elevation both matter, says the U.S. Department of Energy.
Water flows from a reservoir through a large pipe into a turbine and generator; power lines carry the resulting electricity away.

A white LED can use a blue LED with a phosphor coating to produce white light. Tiny conversion, big room glow.

GFCI and AFCI sound like alphabet soup, but they watch for different trouble: ground-fault shock risk versus arcing that can start fires.

A GFCI compares current going out with current coming back. A tiny mismatch can trip it in a blink, because electricity sometimes takes a detour.
A cutaway GFCI diagram shows blue and teal current paths passing through a circular sensor; a small red dotted path branches toward ground.

Some tidal turbine designs are built to capture currents in both directions—as the tide floods in and ebbs out.

The electricity leaving a power plant isn’t booked to one specific wire route. It spreads across connected transmission lines like flow through joined pipes.
Wind and hydro power sources connect through a branching transmission network to homes.

Transformers can raise voltage before long-distance transmission. For the same power, higher voltage means lower current—and less energy lost along the way.

Pumped-storage hydropower is a gravity battery: water flows downhill to generate electricity, then gets pumped uphill again when demand is lower.
Two reservoirs at different heights connect through a turbine and pipe, with arrows showing water moving downhill and uphill.

Franklin’s kite experiment wasn’t an attempt to get struck by lightning. He flew it as a storm brewed, testing an idea about electrical charge.
Benjamin Franklin flies a kite from beneath a small shelter as a storm brews in the distance.

Atoms are mostly empty space. EIA’s scale analogy: a nucleus the size of a tennis ball, with the atom about as wide as a 1,450-foot stadium.
A tiny nucleus is shown at the center of a large spherical atom outline beside a stadium for scale.

Microwaves don’t cook food from the inside out. The outer layers heat first; heat then travels inward. The microwave myth is officially busted.
Microwave waves reflect inside an oven and heat food in a bowl.

A capacitor stores electrical energy, then releases it when a circuit needs it. Tiny component, quick little charge reservoir.
Two parallel capacitor plates hold opposite charges, with a small circuit symbol beside them.

Some crystals produce an electrical charge when squeezed. That pressure-to-voltage trick is the piezoelectric effect—a tap transformed into a signal.
A crystal between two plates is compressed; a small electrical signal travels to a meter.

A heat pump can move heat indoors in winter and outdoors in summer. It’s the same idea as a fridge, switched around for comfort.

A microphone does an electrical translation: sound waves become a signal that can be recorded and amplified.
Sound waves from a speaker enter a microphone; a waveform travels along its cable to a small recorder.

Geothermal power starts with heat below ground. In some plants, underground fluid or steam drives equipment that generates electricity.

Microwaves and visible light are both electromagnetic radiation. Your eyes detect only one small slice of the full spectrum.

Regenerative braking turns some vehicle motion back into electricity. The motor helps slow the wheels while sending energy to the battery.

In an induction cooktop, a magnetic field induces currents directly in compatible cookware. The pan heats from within.

A hydrogen fuel cell can keep making electricity while fuel and oxygen are supplied. It is battery-like, but it does not need recharging.
