Answer:
3 A
Explanation:
The relationship between voltage, current and resistance in a conductor is expressed by Ohm's law, which states that:
where:
V is the potential difference across the conductor
R is the resistance of the conductor
I is the current flowing through it
In this problem, for this flashlight we have:
V = 90 V is the potential difference
is the resistance of the flashlight
Solving for I, we find the current:
Answer : The excess of electrons on the penny are, electrons
Solution : Given,
Total charge =
Charge on electron =
Formula used :
Now put all the given values in this formula, we get the excess of electrons present on the penny.
Therefore, the excess of electrons on the penny are, electrons
