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

September 14, 2021 | education

| 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.
