Determine the current in a conductor with a resistance of 25 ohms at the ends of which the voltage is 7.5V.
| September 3, 2021 | education
To determine the current in the conductor, we apply Ohm’s law for the section of the circuit: we divide the voltage value at the ends of the conductor by the resistance of the conductor.
I = U / R, according to the condition of the problem: U = 7.5 V, R = 25 Ohm.
Let’s do the calculation:
I = U / R = 7.5 / 25 = 0.3 A.
Answer: The current in the conductor is 0.3 A.
