Answer: The correct answer is "igniting the gas-air mixture".

Explanation:

Internal combustion engine is a heat engine. Here, the combustion of the fuel occurs with air.

Internal combustion is fed with fossil fuel like petroleum, natural gas product such as gasoline.

The expansion of high temperature and high pressure gases are produced by the combustion. These gases apply the direct force to some component of engine.

Therefore, the heat is supplied for the hot reservoir in car's engine by igniting the gas-air mixture.

Before we dive into how electricity is used around the home it is worth putting household electricity use in perspective.

Household electricity use generally makes up about a third of total electricity consumption in most developed nations. Using data from the European Union we can give an example of how electricity demand is split among different sectors.

A transformer has 18 turns of wire in its primary coil and 90 turns in its secondary coil. An alternating voltage with an effect

Answer:

$I_s=5.8A$

Explanation:

Not considering any type of losses in the transformer, the input power in the primary is equal to the output power in the secondary:

$P_p=P_s$

So:

$V_p*I_p=V_s*I_s$

Where:

$V_p=Voltage\hspace{3}in\hspace{3}the\hspace{3}primary\hspace{3}coil\\V_s=Voltage\hspace{3}in\hspace{3}the\hspace{3}secondary\hspace{3}coil\\I_p=Current\hspace{3}in\hspace{3}the\hspace{3}primary\hspace{3}coil\\I_s=Current\hspace{3}in\hspace{3}the\hspace{3}secondary\hspace{3}coil$
