In the circuit shown at the right, a voltage of 6 V pushes charge through a single resistor of 2 W. According to Ohm's law, the current in the resistor, and therefore in the whole circuit, is ____ A.
If a second identical lamp is added, as on the left, the 6-V battery must push charge through a total resistance of ___ ohms.
The current in the circuit is then ___ A.
The equivalent resistance of three 4-ohm resistors in series is ___ ohm(s).
Does current flow through a resistor or across a resistor?
through
across
Is voltage established through a resistor or across a resistor?
through
across
Does current in the lamps occur simultaneously, or does charge flow first through one lamp, then the other, and finally the last in turn?
simultaneously
one at a time
Refer to the following information for the next seven questions.
Circuits
a
and
b
below are identical with all bulbs rated at equal wattage and therefore equal resistance. The only difference between the circuits is that Bulb 5 has a short circuit, as shown.
