Question 1 of 20u7a0ODsGZzNbwFdZvki7

What capacity in amperes does a storage battery need to be in order to operate a 50 watt transmitter for 6 hours? Assume a continuous transmitter load of 70% of the key-locked demand of 40 A, and an emergency light load of 1.5 A.

🔍 Key Concepts

• Ampere-hours (Ah) as capacity = current (A) × time (hours) • How to apply a percentage load (70% of 40 A) to find the actual current drawn by the transmitter • Adding together simultaneous loads (transmitter + emergency light) before multiplying by time

💭 Think About

• First, what is 70% of the 40 A key-locked demand, and what does that represent in terms of actual transmitter current? • Once you know the transmitter current, what is the total current when you add the emergency light load? • After you have the total current, how do you use time (6 hours) to convert that into required ampere-hours, and how does your result compare with the multiple-choice options?

✅ Before You Answer

• Be sure you used 0.70 × 40 A to get the continuous transmitter load before adding the 1.5 A light load. • Confirm that you multiplied the combined current by 6 hours to get ampere-hours (Ah). • Check that your calculated ampere-hour value is compared carefully to the choices; if it doesn’t match closely, reconsider your current calculation or rounding.
