Question
If a second bulb is added in series to a circuit with a single bulb, does the resistance of the circuit increase, decrease, or remain the same? Does the current through the battery increase, decrease, or remain the same? Why?
Step 1
Let's denote this resistance as R1. The current through the battery, according to Ohm's law (V = IR), is I = V/R1, where V is the voltage of the battery. Show more…

When a bulb is added in parallel to a circuit with a single bulb, does the resistance of the circuit increase, decrease, or remain the same? Does current increase, decrease, or remain the same? Why?
If a string of five bulbs in series is added in parallel to a single bulb connected to a battery, you find that the brightness of the original bulb does not change. Has the current through the battery increased, decreased, or stayed the same? Has the resistance of the circuit increased, decreased, or stayed the same? Explain.
Would the resistance of the circuit in the preceding figure increase, decrease, or stay the same if bulb A were removed from its socket? What if bulb C were removed instead? Explain.
