Voltage = Water Pressure
Drag the slider or pick a preset to see how tank height (voltage) moves the pressure gauge
Tank height = voltage
high
low
Pressure gauge
reads the voltage
Water wheel = load
Low voltage
High voltage
Voltage: 50%
AA battery (1.5V)
Car battery (12V)
Wall outlet (120V)
Power line (high V)
Tank height
= voltage (electrical pressure)
Pipe / flow
= current (amps)
Narrow pipe
= resistance (ohms)
Water wheel
= the load (motor, bulb, etc.)
