A flashlight bulb uses 2.4 W of power when the current in the bulb is 0.8 A. What is the voltage difference?
2 answers:
Answer:
3 Volts
Explanation:
Because Power = Voltage x Current, so if you substitute the values into the equation, it would be :
2.4 W = Voltage x 0.8 A
Then if you rearrange the equation, it would be :
2.4 W / 0.8 A = Voltage
Which is :
3 V = Voltage
Answer:
3 Volts.
