Ohm's Law

The video tutorial explains the concept of water pressure and its relation to height. It introduces potential difference and its similarity to water pressure, followed by an explanation of Ohm's Law, which describes the relationship between voltage, current, and resistance. The tutorial discusses the properties of conductors and insulators, and demonstrates practical applications of Ohm's Law through calculations of current and voltage in circuits.

How does resistance affect the flow of current?

What are resistors and their purpose in a circuit?

Calculate the current flow in a 100 ohm resistor connected to a 20 volt supply using Ohm's law.
