🔍 Key Concepts

• Relationship between power, voltage, and resistance in a resistor • How parallel circuits share voltage across each branch • Each resistor’s individual wattage rating as the limiting factor

💭 Think About

• What formula links power, voltage, and resistance for a single resistor, and how can you solve it for the maximum voltage on that resistor? • In a parallel circuit, how does the voltage across each resistor compare? • Which resistor will reach its wattage limit first as voltage increases, and what does that mean for the maximum safe voltage for the whole circuit?

✅ Before You Answer

• Use the correct formula: P, V, and R must be in consistent units (watts, volts, ohms). • Calculate the maximum allowable voltage for each resistor separately, using its own wattage rating. • The overall maximum voltage for the parallel circuit is limited by the resistor that allows the lower maximum voltage.
