Electronic Principles
Which one of the following statements is true for current flowing in a series circuit?

The total current in a series circuit is equal to the sum of the currents flowing through the individual components in the circuit

The amount of current flow through each part of a series circuit can be different, depending on the resistance of each part and the amount of voltage applied to it

The same current flows through every part of a series circuit

The total current in a series circuit is equal to the total voltage multiplied by the total resistance
