Voltage u = 80V is applied to the conductor with resistance r = 40 Ohm. What is the current strength i in the conductor

According to Ohm’s law, the current in a conductor will be directly proportional to the effective voltage and inversely proportional to the electrical resistance of this conductor.
I = U / R, where U is voltage (U = 80 V), R is resistance (R = 40 ohms).
Let’s calculate the current strength:
I = U / R = 80/40 = 2 A.
Answer. The current in the conductor is 2 A.
