Project - Analysis of a practical automotive wiring circuit

Identify each of the major elements in the above automotive wiring diagram

If the total load is 10A from battery, what should be the fuse rating?

If 500W is the load, what is the voltage and capacity of battery you recommend?

For the above question we can use voltage of 12V

capacity = product of load of to the time

= 12000wh

Identify any two elements which are connected parallel to each other. Why they are connected in parallel?

Identify any two elements which are connected in series. Why they are connected in series?

The battery and Starter are connected in series because the battery provides electrical energy to start the starter
