Series and Parallel Circuits

In a series circuit, if the potential difference across R1 is V volts, the potential difference across R2 would equal

(60-V) volts

In a series circuit, if resistor R2 is removed and replaced by a resistor of lower value, the resistance of the circuit will

decrease

Which quantity must be the same for each component in any series circuit?

current

In a parallel circuit, if resistance R2 were removed, the potential difference across R1 would

remain the same

In a parallel circuit, if resistance R2 were removed, the current in ammeter A would

decrease

In a parallel ciruit, compared to the potential difference across the source, the potential difference across R2 is

the same

If another resistance were added to the circuit in parallel, the equivalent resistance of the circuit

decrease

When only one lightbulb blows out, an entire string of decorative lights goes out. The lights in this string must be connected in

series with one current pathway

What is the power of the 30 ohm resistor?

4.8 W

Where should an ammeter be located?

Ammeter at 1 (before the split) and voltmeter at 4 ( by the power source
