A2 V
B4 V
C3 V
D5V
Answer:
A. 2 V
Read Explanation:
The correct answer is calculated based on Ohm's law and the circuit configuration, yielding a 2 V potential drop across the 4 Ω resistor. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant. In the equation, the constant of proportionality, R, is called Resistance and has units of ohms, with the symbol Ω.
