Will the current in a lightbulb connected to 220 V be more or less than when the bulb is connected to 110 V? How much?
To Compare: The currents in the lightbulb when connected to different voltage.
Explanation of Solution
Introduction:
As per Ohm’s law, the current
According to Ohm’s law, more current would flow in the lightbulb when it would be connected larger voltage i.e. 220 V.
The ratio of the amount of current is:
Conclusion:
The amount of current that flows in the lightbulb connected to 220 V is double to that when connected to 110 V.
