🔍 Key Concepts

• Behavior of total resistance in parallel circuits when more branches are added • Relationship between total resistance, current, and Ohm's Law (V = I × R) • Difference between line voltage (source voltage) and load current in a simple DC circuit

💭 Think About

• When you add another branch in parallel, are you giving current more paths or fewer paths to flow? How does that affect the overall opposition to current (resistance)? • If the supply voltage stays the same, what happens to the total current when the total resistance goes up or down? Use Ohm’s Law to think this through. • Is the line voltage of a power source (like a battery or generator) normally changed just because you add more parallel loads, assuming the source is ideal?

✅ Before You Answer

• Be clear on how total resistance in parallel compares to the smallest individual branch resistance. • Use Ohm’s Law: if V is constant, check how a change in R_total affects I_total. • Check whether adding parallel loads typically changes the source (line) voltage in exam-style ideal circuit questions.
