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

The total current in a parallel circuit is always less than the smallest amount of current
The same current always flows through every part of a parallel circuit
None of these
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 total current in a parallel circuit is equal to the total voltage multiplied by the total resistance

Electronic Principles
The core of an electromagnet is said to be in saturation when:

changing the polarity of the current in the coil changes the polarity of the magnetic field around the core
the core is permitted to move freely within the coil
frequent changes in the direction of current through the coil causes heating effects in the core material
an increase in current through the coil causes no further increase in the mmf
None of these
