CT111 MIDTERM

An atom's atomic number is determined by the number of:

• neutrons minus protons

• protons

• electrons

• neutrons

A voltage will influence current only if the circuit is:

• open

• insulated

• high resistance

• closed

Primary batteries, unlike secondary batteries, may be:

• charged once

• used once

• recharged over and over

• stored indefinitely

The negative and positive charge symbols are assigned (in that order) to the:

• proton and electron

• electron and proton

• atom and nucleus

• electron and element

If the current in a circuit equals 0 A, it is likely that the

• voltage is too high

• resistance is too low

• circuit has a short

• circuit is open

What are the unit and symbol for current?

• Ampere, A

• Coulomb, I

• Ampere, Q

• Ampere, I

Which part of an atom has no electrical charge?

• Electron

• Neutron

• Proton

• All of the above

Which voltage source converts chemical energy to electrical energy?

• Electrical generator

• Battery

• Solar cell

• Electronic power supply

A switch is a device that:

• short circuits complex circuits

• holds a fuse

• has double poles

• opens or completes a current path

The term used to designate electrical pressure is:

• voltage

• current

• resistance

• conductance
