🔍 Key Concepts

• Power (watts), voltage (volts), and current (amps) relationship: P = V × I • Converting ampere-hours to watt-hours using battery voltage • Total load power when more than one device is connected

💭 Think About

• First, combine the receiver and RADAR power requirements: what is the total wattage the battery must supply? • Using the battery’s 8 ampere-hour rating and 12.6 volts, how many watt-hours of energy does the battery store? • Once you know the battery’s watt-hours and the load’s total watts, how do you find time in hours?

✅ Before You Answer

• Be sure you convert ampere-hours to watt-hours using the given 12.6 volts before finding time. • Confirm that you have added both device power consumptions to get the correct total load in watts. • Before choosing an answer, check if your result is in realistic range (does a small 8 Ah battery really run a 350 W load for many hours?).
