Abattery operating a large flashlight produces a current of 2 amperes in a lightbulb that has a resistance of 2.4 ohms. the voltage of the battery is:

Voltage of the battery = 4.8 volt

Explanation:

It is given that the flashlight produces a current of 2 ampere

So current  i = 2A

And the resistance R = 2.4 ohm

We have to find the voltage of the battery

According to ohm's law voltage of the battery is given by = current × resistance

So voltage = 2×2.4 =4.8 volt

The voltage of the battery depends on the current and resistance.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
