How to find the voltage on each conductor and the total voltage if the current in the circuit is 0.5 A. the resistance of the first conductor is 8 ohms, the second is 12 ohms.

Given:

R1 = 8 Ohm – the value of the first resistance in the circuit;

R2 = 12 Ohm – the value of the second resistance in the circuit;

I = 0.5 Ampere – current strength throughout the entire section of the electrical circuit.

It is required to determine U1, U2 and U (Volts) – the voltage of the electric current at the first resistance, at the second resistance and throughout the entire circuit.

Since the problem statement is not specified, we assume that the resistances are connected in series.

Then, according to Ohm’s law:

U1 = R1 * I = 8 * 0.5 = 4 Volts.

U2 = R2 * I = 12 * 0.5 = 6 Volts.

U = U1 + U2 = 4 + 6 = 10 Volts.

Answer: the voltage on the first and second conductors is 4 and 6 Volts, respectively, the total voltage on the section of the electrical circuit is 10 Volts.
