Determine the voltage in the section of the circuit with a resistance of 6.2 ohms if a current of 0.5 A passes through this section.

According to Ohm’s law, the current in the circuit will be directly proportional to the voltage in the section of the circuit and inversely proportional to the resistance.
I = U / R, where I is the current in the circuit (I = 0.5 A), U is the voltage at the section of the circuit (V), R is the resistance (R = 6.2 Ohms).
Let us express and calculate the voltage on the section of the circuit:
U = I * R = 0.5 * 6.2 = 3.1 V.
Answer: The voltage on the circuit section is 3.1 V.
