Equivalent Resistance Formula

Question 1: What is the “equivalent resistance” formula in the Series combination?

Answer:

The “equivalent resistance” formula in the Series combination is given below,

R_eq = R₁ + R₂ + R₃ + ….. + R_n

Question 2: What is the condition for the series combination of resistance?

Answer:

For the resistor to be connected in series combination the important conditions are,

• The current passing through each resistor is the must be same.
• The resistors are connected in a linear manner.

Question 3: What is the “equivalent resistance” formula in the Parallel combination?

Answer:

The “equivalent resistance” formula in the Parallel combination is given below,

1/R_eq = 1/R₁ + 1/R₂ + 1/R₃ + ….. + 1/R_n

Question 4: What is the condition for the parallel combination of resistance?

Answer:

For the resistor to be connected in parallel combination the important conditions are,

• The voltage difference across each resistor is the same.
• The resistors are connected parallel to each other.

Equivalent resistance is defined as the total resistance of the circuit for the resistors connected in series or parallel combination. Resistors are electrical devices that limit the current flow in a circuit and obey Ohm’s law, V = IR. A circuit may have more than one resistor present due to which equivalent resistance is evaluated accordingly. The value of current and voltage depends on the orientation of resistors in the circuit. 

In this article, we will learn about the Equivalent Resistance Formula in Series and Parallel combinations in detail.
