It's the power that ultimately causes the filament to get hot and emit visible black body radiation. Power is voltage times current, so both matter. However, you can only control one degree of freedom. The bulb dictates the other.
WebThe first step to solving any problem is to write down what is asked of us. We are asked to calculate the power dissipated in the bulb. The next step is to write down what is given to us. We are given the rating. The rating is 10 volt, 50 watt. And we're also given the voltage across it is five volt. Web2.
