THE EQUIVALENT SERIES RESISTANCE IS :
Req = R1 + R2 + R3
THE CURRENT OF THE CIRCUIT IS :
I = U / (R1 + R2 + R3 )
T SERIES RESISTOR CIRCUIT
When we connect resistors in a series circuit
the current which flows through each one of
them it’s of the same value I.
We can find the equivalent resistance if we
add the values of all resistors of the circuit.
That means that the equivalent resistance is
of greater value than the rest of them
separately.
SERIES RESISTOR CIRCUIT
we can find the source voltage:
E = U1 + U2 + U3.
The source voltage is divided in as
many parts as the number of the
resistors in the circuit.
We measure the greater part of the
voltage on the resistor with the
greater value.
