ANS(2)

Fuse: If an appliance malfunctions or a close circuit results in an excessive current flow, a wire inside the fuse melts to break the circuit. By doing so, it protects the wiring and appliances from any high current changes.

Battery: One or more electrochemical cells with external connections for powering electrical devices make up a battery, which is a source of electric power. A battery's positive terminal functions as the cathode and its negative terminal as the anode while it is supplying electricity.

Generator: An electric generator is a machine that transforms mechanical energy from an outside source into electrical energy.

ANS(3)

Given,

Total load(I)= 10A

From Hint: Battery Voltage= 12 V

We know, Power(P)= V*I

P=12V*10A

P=120W

Fuse Rating, I= (P*1.5)/V

I= (120*1.5)/14.5

I=15A

To avoid short circuit , fuse rating should be greater than total load.

ANS(4)

given ,

I= 10A (previous question)

P= 500W

we know,

P= V*I

V=P/I

V=500/10

V=50V

Then, Capacity(C)= I*T

Assume , Time= 1 h

C=10* 1

C= 10Ah

ANS(5)

Horn : High and low tones are alternated in parallel, and the primary sound frequencies of these signals are harmoniously combined.

All Lights: In a parallel circuit, each light has its own circuit. The sum of the separate currents is the overall current. Each light uses the same voltage. In a parallel circuit, the other lights continue to illuminate even if one light malfunctions, unlike in a series circuit.

ANS(6)

Battery : To increase the driveability and energy efficiency, batteries are connected in series with high voltage.

Ammeter: Connected in series to measure the amount of current flowing in the main circuit.
