Final answer:
Using Ohm's Law, which is I = V / R, the current in a circuit with 52 ohms of resistance and a potential difference of 22.5 V is calculated to be approximately 0.43 A.
Step-by-step explanation:
To calculate the current in a circuit with a resistance of 52 ohms and a potential difference of 22.5 V, we use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). Thus, I = V / R.
Substituting the values given:
I = 22.5 V / 52 Ω = 0.43269230769 A.
When rounded to two decimal places, the current is approximately 0.43 A, which corresponds to option A).
