Exam 10: Static and Current Electricity

Two charged particles repel each other with a force F. If the charge of one of the particles is doubled and the distance between them is also doubled, then the force will be

Two lamps, one with a thick filament and one with a thin filament, are connected in parallel to a battery. The voltage is greatest across the lamp with the

A circuit is powered with a battery. Charge flows

There are electrons in the filament of the ac lamp in your bedroom. When you turn on the lamp and it glows, the glowing comes from

When we say an appliance "uses up electricity," we really are saying that

The electrical force between charges depends only on the the charges

The current through two identical light bulbs connected in series is 0.25 A. The voltage across both bulbs is 110 V. The resistance of a single light bulb is

The net charge on a charged capacitor depends on

Particle A has twice the charge of nearby particle B. Compared to the force on Particle A, the force on Particle B is

An electrical diode is useful for

Which statement is correct?

After a capacitor is fully charged, the total number of electrons it contains

The direction of an electric field is the direction of the force that the field would exert on

Three resistors, 1-ohm, 2-ohm, and 3- ohm are connected in parallel. If they were connected in series instead their equivalent resistance would be

The fundamental force underlying all chemical reactions is

As more lamps are put into a parallel circuit, the overall current in the power source

A 10-ohm resistor has a 5-A current in it. What is the voltage across the resistor?

Rub electrons from your hair with a comb and the comb becomes

When the distance between two charges is halved, the electrical force between the charges

In a 110-volt circuit containing a lamp in series with the voltage source,
