To solve the presented problem, you first need to write down the Ohm’s law formula:
I = U / R,
where U is the voltage of the circuit,
R is the resistance of the conductor,
I is the current strength of the conductor.
Knowing the current strength of the conductor and its resistance, we can calculate the voltage of the circuit. Let’s derive it from the written formula:
U = IR2 = 2 A * 12 Ohm = 24 V.
This voltage will be equal to the voltage of all conductors, since the circuit connection is parallel, and with it:
U = U1 = U2 = U3 = 24 V.
Answer: 24 V.
