When dealing with electrical circuits, understanding the concept of total resistance is crucial for determining the overall behavior of the circuit. In this article, we will explore how to calculate the total resistance in a circuit that contains both series and parallel components.
Series and Parallel Circuits
Before diving into the calculation, let's briefly discuss the difference between series and parallel circuits. In a series circuit, components are connected one after the other, and the current flows through each component in sequence. In a parallel circuit, components are connected between the same two points, and the current divides among the components.
Calculating Total Resistance in a Series Circuit
When components are connected in series, the total resistance is simply the sum of the individual resistances. This is because the current flows through each component in sequence, and the voltage drop across each component adds up.
Calculating Total Resistance in a Parallel Circuit
When components are connected in parallel, the total resistance is calculated using the formula:
1/R_total = 1/R_1 + 1/R_2 + ... + 1/R_n
where R_total is the total resistance, and R_1, R_2, ..., R_n are the individual resistances.
Calculating Total Resistance in a Circuit with Series and Parallel Components
Now, let's apply these concepts to the given problem. We have a $10 \Omega$ resistor connected in series to a parallel group containing a $60 \Omega$ resistor and a $5 \Omega$ resistor.
To calculate the total resistance, we first need to calculate the total resistance of the parallel group. Using the formula above, we get:
1/R_parallel = 1/60 + 1/5 = 1/60 + 12/60 = 13/60 R_parallel = 60/13 ≈ 4.62 Ω
Now, we can calculate the total resistance of the circuit by adding the series resistance to the parallel resistance:
R_total = R_series + R_parallel = 10 + 4.62 ≈ 14.62 Ω
However, this is not the only possible answer. We can also calculate the total resistance using the formula:
