2. RESISTOR
• A resistor is an electrical component that limits or regulates the flow of
electrical current in an electronic circuit.
• A resistor is a passive two-terminal electrical component that implements
electrical resistance as a circuit element. In electronic circuits, resistors are
used to reduce current flow, adjust signal levels, to divide voltages, bias
active elements, and terminate transmission lines, among other uses.
• The electrical resistance of a resistor is measured in ohms. The symbol for
an ohm is the Greek capital-omega: Ω.

4. RESISTORS IN SERIES
Resistors are said to be in series when the current flowing
through all the resistors is the same. These resistors are connected
from head to tail in series. The overall resistance of the circuit is
equal to the sum of individual resistance values.
Resistors in Series Formula
Rtotal = R1 + R2 + R3 +……+Rn

5. Resistors in Parallel
Resistors are said to be in parallel when the terminals of resistors
are connected to the same two nodes. Resistors in parallel share
the same voltage at their terminals.
