    Voltage = abeyant amid two charges.

    Defined as the acquired of the alteration linkage:

    $V(t)=frac$

    Current = breeze of electrons

    Defined as the amount of change of the charge:

    $I(t)=frac$

    There are 3 ambit in an electrical circuit:

    Resistance =

    $R=frac$

    In a resistor voltage and accepted are in sync.

    $V(t)=Ri(t)$

    In capacitors voltage leads current. Capacitors are acceptable as a low canyon filter.

    $V(t)=frac\; int\; i(t)dt$

    In inductors accepted leads voltage. Accepted equals the abrogating acquired of the voltage. Inductors are acceptable as a top canyon filter.

    $V(t)=Lfrac$

    relationship amid voltage and current

    $P=VI$

    in a ambit

    in alternation voltage drops and accepted stays constant

    in alongside voltage stays connected and accepted divides according to the resistance

    voltage stays connected in alongside and accepted drops in p

    pizoelectric = a clear beneath compression creates current

    transformers

    vacuum tube = electron emitter in a exhaustion

    integrated ambit a semiconductor benumbed with impurities

    group 4 elements benumbed with accumulation 3 and 5
