What current flows through a 12 kOhm conductor if the voltage across it is 240V?
| July 24, 2021 | education
R = 12 kOhm = 12000 Ohm.
U = 240 V.
I -?
According to Ohm’s law for a section of a circuit, the current I in the conductor is directly proportional to the voltage at the ends of the conductor U and inversely proportional to the resistance of the conductor R: I = U / R.
I = 240 V / 12000 Ohm = 0.02 A.
Answer: the current in the conductor is I = 0.02 A.
