Which one of the following statements is true for current flowing in a parallel circuit?
Options: The amount of current flow through each branch of a parallel circuit can be different, depending on the resistance of each branch part and the amount of voltage applied to it, The same current always flows through every part of a parallel circuit, The total current in a parallel circuit is equal to the total voltage multiplied by the total resistance, The total current in a parallel circuit is always less than the smallest amount of current
