The total resistance in the series circuit with three resistances of 10 Ω, 20 Ω, and 30Ω, is 60 Ω (option A)
How to calculate the total resistance of the circuit?
The total resistance of a circuit in series connection is written according the following formula:
R = R₁ + R₂ + R₃ +...+ Rₙ
Where
- R is the total resistance
- R₁ is the first resistance
- R₂ is the second resistance
- R₂ is the third resistance
- Rₙ could be a fourth, fifth or sixth resistance
Now, we have three resistance in the circuit. Thus, we can calculate the total resistance in the circuit as follow:
- Resistor 1 (R₁) = 10 Ω
- Resistor 2 (R₂) = 20 Ω
- Resistor 3 (R₃) = 30 Ω
- Total resistance (R) = ?
R = R₁ + R₂ + R₃
R = 10 + 20 + 30
R = 60 Ω
Therefore, the current answer is option A
