resistors in series share the same current, and resistors in parallel share same voltage is this always true? or exist some exceptions? thanks
In a series circuit, resistors are connected one after the other, so the current flows through each resistor in turn. In a parallel circuit, resistors are connected side by side, so the current is split between them.
To calculate the total resistance in a series circuit, simply add the resistance of each individual resistor together.
To calculate the total resistance in a parallel circuit, use the formula 1/Rtotal = 1/R1 + 1/R2 + 1/R3... where R1, R2, R3, etc. are the resistance values of each individual resistor.
In a series circuit, the current remains constant throughout the circuit. This means that the same amount of current flows through each resistor.
In a parallel circuit, the voltage across each resistor remains the same, while the total voltage across the circuit is equal to the sum of the individual voltages. This means that the current is divided between the resistors, but the voltage remains constant.
