Current
It is the Flow of Electron, Unit (I) = Ampere
Voltage
The potential difference between more electrons and less electrons is called voltage.
AC Current / DC Current
AC = Alternative Current, The current that comes to our house is AC current. This current cannot be stored.
DC = Direct Current, AC current can be converted to DC with the help of an inverter. This current can be stored in the battery.
Resistance
Blocking the flow of electrons is the function of resistance. If the resistance is high, the current flow will decrease.
Ohm’s Law
Ohm’s Law: V = I.R (V = Voltage, I = Current, R = Resistance)
We use resistance to increase or decrease fan speed at home.
220 (Voltage) = 22 (Current)*10 (Resistance) – Here 10 resistance is given at fan speed, for which only 22 Ampere current is passing. For this the fan will rotate very slowly.
220 (Voltage) = 44 (Current)*5 (Resistance) – Here 5 resistance is given at fan speed, for which only 44 Ampere current is passing. For this the fan will spin louder than before.
220 (Voltage) = 110 (Current)*2 (Resistance) – Here 2 resistance is given at fan speed, for which only 100 Ampere current is passing. For this the fan will spin louder than before.
220 (Voltage) = 220 (Current)*1 (Resistance) – Here 1 resistance is given at fan speed, for which 220 Ampere current is passing. Full current is passing. For which the fan will rotate at full speed.
