Question
A resistor has a resistance of 271 Ω. How much current passes through the resistor if there is a potential difference of 120 V across the resistor?
Solution
To find the current passing through the resistor, we can use Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R).
Given: Voltage (V) = 120 V Resistance (R) = 271 Ω
We can substitute these values into Ohm's Law:
I = V / R I = 120 V / 271 Ω
Now, perform the division to find the current:
I = 0.4428 A
So, approximately 0.443 Amperes of current is passing through the resistor.
