A whole set of math can be devised in which the water pressure is analogous to the
current in the circuit. But I was never comfortable with that. It seemed a lot more
intuitive and useful to me ... and when I explain electricity to my kids I always do it
this way ... to draw the analogy between the water pressure at the faucet and the
voltage at the outlet.
What else can I help you with?
In the water analogy of an electric circuit what corresponds to the power supply the resistor and potential difference?
Power supply: Water pump, producing pressure at its output valve.Resistor: A section of pipe. Flow of water loses energy on the way through, due to friction with the pipe's interior wall.Potential difference: Difference in water pressure between the beginning and end of the pipe section.
A water analogy for voltage would?
Voltage in a circuit can be compared to water pressure in a pipe. Just like higher water pressure allows water to flow faster and with more force, higher voltage in a circuit enables electric current to flow more easily and with more energy. Conversely, lower voltage results in slower and weaker flow of electric current, similar to low water pressure leading to a weaker flow of water.
Flow of water and electric current is compared to?
The flow of water is often compared to the flow of electric current. In both cases, the flow is the movement of a substance (water or electrons) from one point to another. The pressure difference in water systems is analogous to the voltage difference in electrical systems, and the flow rate in water systems is similar to the current in electrical systems.
Is voltage electrical pressure?
Yes. If you compare the effect water pressure has on flow rates and from an open tap, more pressure allows more water to flow out of and away from the source. In electrical circuitry, an increase in voltage - say from a battery - will in most cases enable a larger current to flow around the circuit that the battery is connected to. Voltage can be seen as the pressure force pushing another quantity around the loop and that quantity is electrical current . Electrical pressure and the quantity of electricity transmitted can be considered analogous to water flowing in pipes. Electrical pressure is called voltage: the longer the distances, the higher is the pressure (voltage) required to pump the current. That is why, for long distance transmission, high pressure (voltage here) is required, failing which, the power will not reach the destined end. It will dissipate on the way. <><><> We can think of electrical current as the quantity of electricity which will be drawn from the pipeline (= cables for electricity) at the pressure (= voltage) required.
How you would use the water flow to demonstrate a low-voltage electric current?
In a water system, the "voltage" is the water pressure, the flow rate is the "current", and the pipe size is the "resistance". Low-voltage electrical current is equivalent to low-pressure water.

Explain that electrical power is the product of voltage and current with their respective symbols and units?
Volts(v) x Amps (a) = Watts (w) voltage is analogous to water pressure and amperage is analogous to water volume, so wattage is analogous to cu.ft. per minute.
In the water analogy of an electric circuit what corresponds to the charge?
The water itself does.
Why are models and analogies useful when thinking about electricity?
We cannot see the electrons flowing through the conductor. Using an analogy is helpful to somebody trying to understand these concepts. One analogy that is commonly used, is comparing the electron flow to water flowing through a pipe. The speed at which the water flows is analogous to the current. Resistors are compared to making the pipe smaller (restricting the flow). Voltage is compared to pressure - more pressure makes the water move faster through the pipe. These can help students understand how different changes to a circuit can affect the electric current flow through the circuit.
What pushes current through a circuit?
Well, darling, current is pushed through a circuit by a difference in voltage, also known as an electric potential difference. This voltage creates an electric field that exerts a force on the charged particles within the circuit, causing them to move and thus creating an electric current. So, in simpler terms, it's like the electric field playing tug-of-war with the charged particles to get them moving.
Flow of water and electric current is compared to?

The pressure difference in water systems is analogous to the voltage difference in electrical systems, and the flow rate in water systems is similar to the current in electrical systems.
What moves water besides currents and electric charge?
gravity, water pressure, air pressure, buckets, etc.
What is electrical pressure?
Electro motive force = EMF = Voltage.
What is the name of the electrical pressure that causes current to flow in a circuit?
Electrical pressure is called "electro-motive force" (EMF). It is measured in volts. Pressure and the quantity of electricity transmitted can be considered analogous to pressure and quantity of water flowing in pipes: the longer the distance, the higher is the pressure (called the "voltage" for electricity) that is necessary to pump the flow of water (called the "flow of electrical charge, which is also known as the "electric current"). That is why, for long distance transmission, high pressure (voltage for electricity) is required, failing which, the current - and therefore the power - will not reach the intended destination. Instead, it will be lost (also called "dissipate") along the way. We can think of electrical current as the quantity of electricity which will be drawn from the pipeline (= cables for electricity) at the pressure (= voltage) required.
Is voltage electrical pressure?

Can an electric water heater explode under certain circumstances?
Yes, an electric water heater can explode under certain circumstances, such as when the pressure relief valve malfunctions or when there is a buildup of pressure due to overheating.
