DC CIRCUIT TERMINOLOGY
Basic DC Theory
A short circuit is a circuit
Figure 15 Short Circuit
which offers very little
resistance to current flow
and can cause dangerously
high current flow through a
circuit (Figure 15).
Short
circuits are usually caused
by an inadvertent connection
between two points in a
circuit which offers little or
no resistance to current flow.
Shorting resistor R in Figure
15 will probably cause the
fuse to blow.
Series Circuit
A series circuit is a circuit where there is only one path for current flow. In a series circuit
(Figure 16), the current will be the same throughout the circuit. This means that the current flow
through R1 is the same as the current flow through R2 and R3.
