Question

Please help. I will medal
(Match these up)

1. PSI ammeter
2. pipes battery
3. pump switch
4. valve conductors
5. restriction resistance
6. water meter volts

Answer 1

Which ones are you stuck on? I'd be happy to help

Answer 2

Well all of them. They have this picture with electricity flow vs water flow. I know that batteries are volts and PSI are pumps but it wont let me connect them

Answer 3

here is the pic

Answer 4

Ah, I see. I think it wants you to connect the circuitry terms with the analogous water system terms. Comparing circuits to piping systems is how many courses introduce circuits as it provides students as its often easier to visualize water flowing through a pipe.

So in this case, a battery, which provides a voltage and drives electrons around a circuit is analogous to a pump, which forces water through pipes

Answer 5

I still don't get it
I have like a little box and i have to put the number of which one it goes to and it wont let me do batteries and volts

Answer 6

Right, because batteries and volts are both electrical terms. Try matching each individual electrical term with its corresponding individual pipe flow term. e.g. a circuits' battery is the equivalent of a pipe system's pump. Try that for the rest of them:

1. PSI in a pipe system is equivalent to ______ in a circuit
2. pipes in a pipe system are equivalent to ______ in a circuit
3. A pump in a pipe system is equivalent to a *battery* in a circuit

etc

Answer 7

resistance turns into amps?

Answer 8

i feel so stupid

Answer 9

Don't feel stupid! Its tricky the first time around.

So resistance in a circuit is what limits or "resists" the flow of current. Say there's a bunch of hair in your shower drain. The water goes through the drain slower if its partially clogged than if there's no hair in the drain at all. In your pipe flow example, the resistor is equivalent to the restriction. The resistor prevents all the current from flowing through at once just like the smaller pipe section prevents all the water from flowing through at once

Answer 10

And you can do the same thing for each part of your circuit. If you turn off a light in your house, its because you are opening a switch (i.e. physically disconnecting the wires) and preventing any current from going through. Thats like if the tap on your kitchen sink is closed all the way. No water can go through because the valve is closed. If you open the switch on the circuit, now electrons can flow through freely because you reconnect the wires. That's the same thing as turning on the water on your sink. You open the valve and the water can flow through

Answer 11

i figured it out

Answer 12

thx!
