Potential difference and the conductor. A cell and a bulb. Some connecting wires. The bulb can be made glow by connecting the wires with the cell.
Your question is not clear. A current is generated when a group of electrons flow through a conductor, and this happens when there is a potential difference between the 2 ends of the conductor. If you want to know how can we start the flow of electrons it is by creating a potential difference in between the 2 ends of the conductor.
Blocks flow of (1) electric current and/or (2) heat
Parallel means 2 straight lines and series circuit means a circuit with only one pathway for current flow
I = E / R = 6 / 12 = 0.5 Ampere
A force has to to be exerted for a distance

For the circuit to be connected all the way round because if there are breaks in the circuit the electricity will not flow back round. and number 2 a battery or a power source because without power where is the electricity coming from to be honest. Hope it helped. Thanks. xx
Everything Depends on the voltage supply ...... Current flow (Amp) = Watt / Voltage the Current flow will be 1 amp if voltage is 1 V the Current flow will be 0.5 amp if voltage is 2 V the Current flow will be 0.25 amp if voltage is 4 V and so on.......
A circuit must have three basic components to make electricity flow. 1. Source of power or electricity. 2. Wires, switches and conductors through which the current can flow. 3. And finally a load to complete the circuit.

You avoid current flow through your body by doing two things... 1.) Turn of the power at the distribution panel. 2.) Make sure you never touch the circuit and any ground at the same time, just in case turning the power off did not actually do so.
the two types of electrical current are AC which stands for Alternating current and DC which stands for direct current. Battery current is direct current. The electrons in alternating current flow one way and then flow in the opposite direction.
1) in inductor there is generation of magnetic field due to flow of current . so there is phase difference in voltage and current . 2)in capacitor there is storage of charges. there is phase diff. 3)But in case of resistor there is no such things are happend . it is only a power dissipating element.therefor there is no phase difference between current and voltage.
Since power is voltage times amperes, in order to double the power while voltage remains the same, you must double the current - 4 amps in this case.
A current of 32 amperes for 2 minutes represents a current flow of 3,840 coulombs.One ampere is one coulomb per second.
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
Current flow would be the same through the resistor, since it's in series, but the voltage would be slightly reduced based on the resistance. If you have 2 resistors in parallel, the current will divide through each resistor, and the voltage stays the same. PLL Ohm's law and water flow - PLL
