Voltage, Current & Resistance

In electronics we are dealing with
voltage, current and resistance in
circuits.
Voltage
Voltage is the electrical force, that
causes current to flow in a circuit. It is
measured in VOLTS .
Electrical Current
Current is the movement of electrical
charge - the flow of electrons other
charged particles through the
electronic circuit. The direction of a
current is opposite to electrons flow
direction. Current is measured in
AMPERES (AMPS, A ).
Resistance
Resistance causes an opposition to
the flow of electricity in a circuit. It is
used to control the amount of voltage
and/or amperage in a circuit. It is
measured in OHMS.
There is a relation between Voltage, Current & Resistance i.e ^V ⁄ _R=I
