Two bulbs marked 200 W-250 V and 100 W-250 V are joined in

Answer:

P = 66.67 W

Explanation:

Joule Heating

It's the process by which the electric current passing through a conductor produces heat.

Also known as Joule's first law or the Joule–Lenz law, states that the power of heating generated by an electrical conductor (P) is proportional to the product of its resistance (R) and the square of the current (I).

It can be described by the equation that follows:

$P = I^2.R$

Also, we can calculate the voltage V with the formula of Ohm's law:

$V = I.R$

Combining both equations, power can be related to the voltage:

$\displaystyle P=\frac{V^2}{R}$

Given the power and the voltage, the resistance can be calculated by solving for R:

$\displaystyle R=\frac{V^2}{P}$

There are two bulbs marked P=200W V=250V and P=100 W V=250.

The first bulb has a resistance of:

$\displaystyle R_1=\frac{250^2}{200}$

$\displaystyle R_1=312.5\Omega$

The first bulb has a resistance of:

$\displaystyle R_2=\frac{250^2}{100}$

$\displaystyle R_1=625\Omega$

When connected in series, the total resistance is

$R = R_1 + R_2=312.5\Omega+625\Omega$

$R=937.5\Omega$

The total power consumed when connecting them to a V=250 V supply is:

$\displaystyle P=\frac{250^2}{937.5}$

P = 66.67 W

What are the energy transfers in a torch?

lapo4ka [179]

Explanation:

The battery is a store of internal energy (shown as chemical energy). The energy is transferred through the wires to the lamp, which then transfers the energy to the surroundings as light. These are the useful energy transfers - we use electric lamps to light up our rooms.

Energy conservation is the process by which one kind of energy changes into a another and when energy is converted this way it's

Sedbober [7]

True. The question describes the idea of energy conservation faithfully. Energy can change forms but remains the same within an isolated system over time. Within such a system, energy cannot be created or destroyed.
