"dc" is direct current which is what batteries use, whereas "ac" is alternating current, which is what your household receptacle uses.
Even though it is connected to a 9 volt source, it is still a resistor.
this action is very dangerous and should not be considered.
In an uninterrupted power supply there has to be a source of power when the electrical utility is not there. The only supply that is available is a battery that is in or connected to the UPS.
When external source such as a battery is connected electrons get specific directions to move and condition starts
a circuit is a round wire that connects through a battery into a lightbulb
Yes, a battery is a source of stored electrical energy that can be used to power various devices and equipment when connected in a circuit. The chemical reactions inside the battery convert stored chemical energy into electrical energy that can be used to produce electricity.
thanks for the answer
battery, generator, alternator, etc.
You "ground" it or connect it to a negative source that is connected got the negative end of the battery
what
A light bulb is not lit when the swtich is not connected to the wire becasue there is no flow of electricity, specifically, flow of electrons. By disconnecting the wire, the bulb is no longer connected to the electricity source.
Consider a battery for a moment. A battery can be a source or sink type of power source. A light bulb would be considered a source current. When a battery or other item is being charged is it considered a sinking source.
