d) Ignition coil

e) Ammeter

f) Foot selector switch

g) Breaker

i) Fuse

j) Current and voltage regulator

2. Genarator: An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy. It uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

Fuse:It is a safety device. The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily.

Breaker:A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire.

Given data;

Total load(I)=10A

fuse rating=?

Voltage(V)=30V [since the typical Car battery voltage is 30V ]

we know that;

P=V*I

P=30*10

P=300KW

fuse rating=I=(P*1.5)/V

I=(300*1.5)/30

I=15A

4. Given data;

I=10A (from the previous question)

P=500W

V=?

C=?

we know that,

From the power formula,

P=V*I

V=P/I

V=500/10

V=50V

capacity (C)= I*T

=10*1

C= 10Ah

5.Horn: parallel switching of high and low tones is used and the main sound frequencies of these signals are harmoniously combined.

All lights:Each light in a parallel circuit has its own circuit. The individual currents add up to the total current. The voltage for each light is the same. As opposed to a series circuit, if one light malfunctions in a parallel circuit, the other lights still light up.

6.Battery:connected in series with high voltage to improve the drivability and energy efficiency

Ammeter:An ammeter is a device which measures the amount of current flowing in a circuit. It is a very low resistance(nearly zero) device. If it will be connected in parallel, it would draw most of the current and would get damaged.
