Hey there, future electrical wizards! ⚡🔌
Have you ever wondered how we can predict the behavior of electric circuits? The answer lies in a fundamental principle known as Ohm's Law. This law is the foundation for understanding how voltage, current, and resistance interact in an electric circuit. Today, we’re going to explore Ohm’s Law, its application in series and parallel circuits, and work through some example problems. Let’s get started!

Total Resistance (Rtotal): Calculate the resistance of parallel sections first, then add the series resistances.
Current (I): Use Ohm's Law to find the current after calculating the total resistance.
Voltage (V): Determine voltage drops across series components and equal voltage across parallel components.
