We can use Ohm's Law to solve this problem:
V = I * R
where V is the voltage, I is the current, and R is the resistance.
We are given V = 25 volts and R = 45 ohms. Solving for I, we get:
I = V / R
I = 25 / 45
I = 0.56 amps (rounded to two decimal places)
Therefore, the current passing through the tracks is 0.56 amps.
An electric train uses a power source of 25 volts. If the train track has a total of 45 ohms of resistance, what is the current passing through the tracks?
