Aresistor is connected to a 3.0 battery. the power dissipated in the resistor is 4.0 a second, identical resistor is connected in series with the first. how much power is dissipated in one of the resistors now?

Power dissipated across any resistance is given by

now it is given that when one resistance of value 3 ohm connected the power dissipated is 4 Watt

now another identical resistance of same value is connected then the current will reduce to half of its initial value.

now power across any one resistance is given by

So now we will have

So now the power will become 1/4 times of initial power

So now the power will be

the answer is kevlar

radiation

explanation:

heat is transmitted by radiation
