what does the electric current in a wire depends on
what does the electric current in a wire depends on The potential difference across which the charge moves. [ he current flow is determined by 2 things: Voltage applied and the Resistance to the flow of current.
Amps = Volts / Resistance measured as Amps = Volts / Ohms
also known as I=E/R which is the same is E=I*R
So, only the potential difference across the resistive circuit and the amount
of resistance to flow determine the current.
B is the correct answer to determine current flow (amps).
The type of power source determines how much voltage might be seen across the load, (a small battery depletes quickly, and the voltage would soon diminish) but current is an instantaneous commodity, and the formula, "Ohms Law" always rules.
