How much current is flowing through a 1 kΩ resistor when apotential difference of 2V is applied across its end ?
Question
Solution
Sure, to find the current flowing through the resistor, we can use Ohm's Law, which states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points, and is inversely proportional to the resistance (R) between them. It is usually formulated as I = V/R.
Given: Voltage (V) = 2V Resistance (R) = 1 kΩ = 1000 Ω
We can substitute these values into the formula:
I = V/R I = 2V / 1000 Ω I = 0.002 A or 2 mA
So, the current flowing through the resistor is 2 milliamperes.
