Solution
We can say that there is an electric current when there is a flow of electrons. This is because electric current is defined as the rate at which charge is flowing.
As for the second question, the current can be calculated using Ohm's law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R).
So, if the voltage is 2.5 V and the resistance is 0.5 Ω, the current would be:
I = V/R I = 2.5V / 0.5Ω I = 5 Amperes
So, the current produced by a voltage of 2.5 V through a resistance of 0.5 Ω is 5 Amperes.
