You could say yes. The usual analogy is the height of a water fall relative to the flow of the water in a stream. If the potential difference is great it is similar to a high fall since the height difference is what drives the water down the falls.
Parallel circuit: The fact that the voltage is the same follows from Kirchoff's Voltage Law. Series circuit: The voltages of the individual resistances must add up to the total voltage. This, too, follows from Kirchoff's Voltage Law. If the resistances have the same values, all of them will drop the same voltage (which, of course, will be less than the total resistance). But if they are different, Kirchoff's current law tells us that the same current must flow through each resistor in series - and the voltages will be different in this case, according to Ohm's law.
'Electricity' is not a quantity; it's the name of a subject area or topic (just like 'chemistry'). So 'current' describes a flow of charge (not 'electricity'), expressed in amperes. 'Voltage' (potential difference) is responsible for 'driving' current, expressed in volts. 'Resistance' is the circuit's opposition to current, expressed in ohms.
Light travels exclusively through space or along optical fibres by the mechanism of electromagnetic propagation. Electrical energy can also do that, in which case it is called microwave radiation or radio waves, but it can also be carried on wires.
The higher voltage source forces current backwards into the lower voltage source, which can damage it or even cause it to explode.
Yes to both.
In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric current to flow through an external circuit.

I assume you mean Voltage, Current and Resistance. Voltage (E)or electromagnetic force is the electrical pressure or force that forces the electrons through any given circuit Current (I)is the flow of those electrons through any given circuit Resistance (R) is anything within the circuit that would restrict the flow of electrons

This is due to Kirchoff's law. The total voltage around a closed loop must be zero.This is related to energy conservation. An electron (for example) needs a certain energy to go from point "A" to point "B", against the electrical forces (voltage, really). Voltage is defined as energy per unit charge. If the electron could, for example, go one way and gain an energy of 5 electron-volts (the energy an electron gains when going through a potential of 5 volts), then go another way and lose 4 electron-volts, this could be used to build a perpetuum mobile - therefore it isn't possible.

Yes to all. -- Electrical current in a toaster produces thermal energy, often known as "heat". -- In a light bulb produces light. -- In the wires dangling from eaqr-buds produces sound. -- In a solenoid coil or motor stator produces magnetic forces.

Electromagnetic energy is the kind of energy which results from the forces generated by electrical charge in accordance with Coulomb's Law.
Electrical charge is a basic property of some particles. According to Coulomb's Law there is a force between charges. This force is associated with potential energy contained in an electric field. This electrical potential is called voltage. When voltage is present, electrically charged particles move (unless prevented from doing so) due to the forces they "feel." The flow of charge is known as electrical current.
Electromagnetic energy is the kind of energy which results from the forces generated by electrical charge in accordance with Coulomb's Law.
Electricity can be defined as the flow of negatively charge particles, called electrons. This flow is only possible in conductors (ex. metals) but not in insulators (ex. glass). As the electrons flow, they have to overcome frictional forces. Friction produces heat. The more friction that is encountered, the more heat is generated. So the current passes quite easily through the copper conductors, generating very little heat. As it reaches the load (heater, lamp etc), the resistance is greater so the bulk of the heat is generated here. Electrical energy is being converted to thermal energy.
