Understanding of series and parallel resistors

 

In an electrical circuit, resistors can be connected in series or in parallel. The connection determines how the resistors behave and how they affect the current and voltage in the circuit.

In a series connection, the resistors are connected end-to-end, so that the current flows through each resistor in turn. In a parallel connection, the resistors are connected side-by-side, so that the current can flow through multiple resistors at the same time.

The relationship between the resistance, current, and voltage in a circuit with resistors connected in series is given by Ohm's law:

V = IR

Where V is the voltage across the resistors, I is the current through the resistors, and R is the total resistance of the circuit.

The total resistance of a circuit with resistors connected in series is equal to the sum of the individual resistances:

R = R1 + R2 + R3 + ...

The relationship between the resistance, current, and voltage in a circuit with resistors connected in parallel is given by the formula for parallel resistance:

1/R = 1/R1 + 1/R2 + 1/R3 + ...

Where R is the total resistance of the circuit and R1, R2, R3, etc. are the individual resistances of the resistors.

By understanding the difference between series and parallel connections and how to calculate the total resistance of a circuit, you can analyze and understand the behavior of circuits with multiple resistors.
