Voltage, Current and Resistance

Mr. Andersen explains the concepts of voltage, current, and resistance using a water analogy. He demonstrates these concepts using a circuit construction kit simulation, highlighting the relationships defined by Ohm's Law. Practical applications and examples are provided to illustrate how changes in voltage and resistance affect current in a circuit.

What happens to the current when the voltage is increased while keeping resistance constant?

Describe the relationship between resistance and current.

How can you determine the voltage if you know the current and resistance?
