The temporarily be the output of a 100-W light bulb is 148 watt.
To find the answer, we need to know about the resistance of the bulb.
<h3>What's the mathematical expression of resistance of the bulb in term of power and voltage?</h3>
- Mathematically, power= voltage²/resistance
- So, resistance= voltage²/power
<h3>What's the resistance of the bulb, if 115 volt is applied to 100 watt bulb?</h3>
Resistance= 115²/100= 132.25 Ohm
<h3>What's the power of the bulb, if 140 volt is applied to it?</h3>
Power= voltage²/resistance
= 140²/132.25
= 148watt
Thus, we can conclude that the temporary output of the bulb is 148 watt.
