You need to connect your doorbell to the electricity in a battery. You should select a material that will accept the flow of electrons.
You can think of a circuit as a loop. In order for electric current to flow through the loop, the \sloop must not contain breaks. In other words, the circuit must \sbe closed. An open circuit has one or more breaks. Most \scircuits have an energy source, wires, a load, and a switch. As \smentioned, energy sources for circuits include generators and \sbatteries.
Machines that generate electricity from mechanical energy are called generators. In this lesson, we’ll focus on batteries. Inside a battery, two kinds of metals build up opposite charges. Negative charges build up on one end of the battery. Positive \scharges build up on the other end of the battery. This is why batteries are marked with \spositive sign (+) and a negative sign (–).

why does discharge in a stream usually increase downstream? group of answer choices because the volume of water in the stream increases with distance from the source because stream velocities increase with distance from the source because the stream is deeper downstream because the frictional resistance decreases downstream
Discharge in a stream usually increase downstream because the volume of water in the stream increases with distance from the source and the main reason of flowing downward is phenomena of gravity and also because stream velocities increase with distance from the source.
What is a Stream and How does it works?
A stream is a body of water that flows on the surface of the Earth. The terms stream and river are frequently used interchangeably, though rivers typically describe larger streams.
Streams require gravity and water to exist. When precipitation falls on the ground, some of it trickles into groundwater, but the majority of it runs downhill as runoff and collects in streams. A watershed, also known as a drainage basin, is the area where water is collected for a stream. Smaller streams frequently merge to form larger streams as they flow downhill. These smaller streams are referred to as tributaries.
