Given:
R1 = 300 Ohm – resistance of the first resistor;
R2 = 75 Ohm – the resistance of the second resistor.
It is required to determine the total resistance of the circuit R (Ohm).
Since, according to the condition of the problem, both resistors are connected in parallel, then:
R = R1 * R2 / (R1 + R2) = 300 * 75 / (300 + 75) = 22500/375 = 60 ohms.
Answer: the total resistance of the circuit section is 60 ohms.
