The electrical circuit consists of 3 series-connected resistances: R1 = 25 Ohm, R2 = 50 Ohm, R3 = 75 Ohm. Determine the resistance of the circuit.
Rfirst = 25 Ohm – resistance of the first resistor;
Rsecond = 50 Ohm – the resistance of the second resistor;
Rthird = 75 Ohm – resistance of the third resistor.
It is required to determine R (Ohm) – the total resistance of the circuit.
According to the problem, all three resistors are connected in series. Then, the total resistance of the circuit will be equal to:
R = R first + R second + R third = 25 + 50 + 75 = 150 ohms.
Answer: The total resistance of the electrical circuit is 150 ohms.
