atoms
The unit of measure for resistance
ohms
ampere
voltage
watts
This is the unit of measure for current
ampere

In a parallel circuit, why is it that when a bulb burns out or is loose, the other bulbs still light up?
because the electric current does not flow
because electric current can be stopped from flowing
because electric current is allowed to pass through a single path
because each connection in the circuit is independent from the others
What kind of circuit is this?
Parallel circuit
Series circuit
What is the disadvantage of the circuit? (More than one answer.)
The brightness of bulb increases when more batteries are connected.
If one of the component is fail, the other components will not function.
The components cannot be controlled by different switches.
What is the advantage of the circuit? (More than one answer.)
The brightness of bulb increases when more batteries are connected in parallel.
If one of the component is fail, the other components will not be affected.
The components can be controlled by different switches.
Which of the following is the actual substance that flows through a circuit?
Voltage
Current
Charge
Resistance

True or False: Heat transfers from an object of higher temperature to an object of lower temperature.
(a)
As energy in the form of heat is added to an ice cube, it begins to melt. What causes melting.
Heat causes the molecules to expanded and forces them apart.
Heat removes thermal energy from the ice cube and causes it to become liquid water.
Adding energy causes the bonds between the hydrogen and oxygen in the ice cube to break.
The transfer of thermal energy to the ice cube causes its molecules to move faster.
How does heat affect the thermal energy of an object that is colder than the air that surrounds it?
Heat decreases the thermal energy of an object as energy moves to the air.
Heat causes the thermal energy of the object to increase as energy moves from the warmer air to the colder object.
Heat has no effect on thermal energy, but it increases the potential energy of an object.
Heat is not related to thermal energy, so it cannot affect the thermal energy of an object.
