Q: According to Ohm’s Law, if more resistive paths are put in a series between a source’s terminals, the current flow would _____.
- increase
- decrease
A: decrease

Q: The equivalent value of all resistances in a circuit is called the _________.

- total resistance
- total conductance
- total equivalent source
A: total resistance

Q: The current taken from a source by a functioning series circuit is called the _____.
- source current
- total voltage
- total current
- None of the above
A: total current

Q: In a series circuit, current flows through each component.   Since current flow has only one path and the current flow is dependent upon the total resistance the source is connected to, the rate of current flow is _____.

- higher in the conductors and less in resistances
- the same throughout the circuit
A: the same throughout the circuit
