Ohm's Law states that the current flowing in a circuit is directly proportional to the applied potential difference and inversely proportional to the resistance in the circuit.
In other words, by doubling the voltage across a circuit the current will also double.
Volt is the unit for Voltage (V).
Amp is the unit for Current (I).
Ohm is the unit for Resistance (R).
In the serial circuit, the current is the same everywhere.
In the parallel circuit, the current splits up when it comes to a branch. The current in all the branches adds up to the current in the main part of the circuit.
Charge conservation is the principle that electric charges can neither be created nor destroyed. The positive charge and the negative charge in the universe are always conserved.
