Equivalent resistance is the total resistance in a circuit, which is a measure of how much the circuit resists the flow of electric current. It is a combination of all the resistances in the circuit, and is represented by the symbol "Req".
In a series circuit, equivalent resistance is calculated by simply adding all the individual resistances together. This is because the current in a series circuit has to pass through each resistor, so the total resistance is the sum of all the resistances.
In a parallel circuit, equivalent resistance is calculated using the formula 1/Req = 1/R1 + 1/R2 + 1/R3 + ... , where R1, R2, R3, etc. are the individual resistances. This is because in a parallel circuit, the current splits up and the total resistance decreases.
In a series circuit, adding more resistors will increase the equivalent resistance. This is because the current has to pass through each resistor, and each resistor adds to the total resistance.
In a parallel circuit, adding more resistors will decrease the equivalent resistance. This is because the current splits up and each resistor has less current passing through it, resulting in a lower total resistance.
