1. Two resistors in series can act together as one resistor with
a resistance called the equivalent resistance. If the resistance of
the two resistors are R1 and
R2, where R1 >
R2, rank the two resistance and the equivalent
resistance in order of small to large. Give a conceptual
explanation.
2. Two resistors in parallel can act together as one resistor
with a resistance called the equivalent resistance. If the
resistance of the two resistors are R1 and
R2,...

combination is connected to a 120V battery. Find
(a) the equivalent
resistance of the parallel resistors,
(b) the total current
provided by the battery.

Series/Parallel Circuits: When unequal resistors are connected
in series across an ideal battery,
the same power is dissipated in each one.
the potential difference across each is the same.
the equivalent resistance of the circuit is equal to the
average of all the resistances.
the current flowing in each is the same.
the equivalent resistance of the circuit is less than that of
the smallest resistor.
