Question

Match the similarities between an electrical circuit and water circuit.

1. PSI
+ voltage
2. pipes
open circuit
3. pump
closed circuit
4. valve
- voltage
5. restriction
resistance
6. water meter
conductors
7. water
switch
8. high pressure output
ammeter
9. low pressure intake
battery
10. valve closed
electrons
11. valve open
amps
12. liters/second
volts

Answer 1

Here are the correct matches (water → electrical), with a brief note for each:

1. PSI → volts (electrical potential)
2. pipes → conductors (wires)
3. pump → battery (voltage source)
4. valve → switch
5. restriction → resistance (resistor)
6. water meter → ammeter (measures flow/current)
7. water → electrons (charge carriers / moving charge)
8. high pressure output → + voltage (positive terminal)
9. low pressure intake → - voltage (negative terminal/ground)
10. valve closed → open circuit (no current flow)
11. valve open → closed circuit (circuit complete; current flows)
12. liters/second → amps (rate of flow = current)

If you want, I can also draw a simple diagram showing these analogies.
