Two resistors are connected in parallel.
a.) If a third resistor is now connected in parallel with the
original two, does the equivalent resistance of the circuit
increase, decrease, or remain the same?
b.) Choose the best explanation from among the
following:
1. The third resistor gives yet another path for current to flow
in the circuit, which means that the equivalent resistance is
less.
2. Adding a resistor generally tends to increase the resistance,
but putting it in parallel...

In a circuit, a parallel combination of six 2.6 kΩ resistors is
connected in series with a parallel combination of four 3.0 kΩ
resistors. The source voltage is 24 V.

resistors, the total current in the circuit is 18.9 mA. How many
resistors were removed?
