Three resistances 2 Ohm 4 Ohm 6 Ohm are connected in series in the circuit.

Three resistances 2 Ohm 4 Ohm 6 Ohm are connected in series in the circuit. What is the equivalent resistance of the circuit?

Given:

R1 = 2 Ohm – the value of the first resistance;

R2 = 4 Ohm – the value of the second resistance;

R3 = 6 Ohm – the value of the third resistance.

It is required to determine Rtot (Ohm) – the equivalent resistance of the circuit.

Since, according to the condition of the problem, all resistances are included in the electrical circuit in series, then to determine the total resistance of the circuit, you must use the following formula:

Rtot = R1 + R2 + R3 = 2 + 4 + 6 = 6 + 6 = 12 ohms.

Answer: the equivalent resistance of the electrical circuit is 12 ohms.
