Electronics
Current is the rate of flow of charge.
= Current [amperes - A]
= Charge [coulombs - C]
= Time [seconds - s]
Voltage is equal to current multiplied by resistance
Power is equal to the product of voltage and current
Electronics is the flow of current through semiconductor devices like silicon and germanium.
Semiconductor devices are those which behave like conductors at higher temperature.
Transistor, diode, SCR are some electronic devices.
