Project - Analysis of a practical automotive wiring circuit
A-1. (a) Battery
(b) Ammeter
(c) Fuse
(d) Starter
A-2. (a) Battery - battery is connection of cell. chemical reaction occuring in cell
of battery and result flow of electricity in circuit. and battery store energy.
battery have two node positive & negetive.
(b) Ammeter - Ammeter is instrument measure flow of current in electrical circuit.
it measure current in ampere (A).
(c) Fuse - fuse is safety device. it provide protection from flow of overcurrent
in electrical circuit .
A-3. If the total load is 10A from battery, fuse rating = 11A
A-4. Load (P) = 500w V=12v
current (I)= P / V
= 500 / 12
= 41.66A
Battery recommend = 42mah
A-5. DDMC light and PLATC light in connected parallel
because of constant voltage in parallel connection current will same light will glow equally.
A-6. Ammeter and Fuse connected in series connection.
because of constant current in series connection.
