Series Resistive Circuits

Question 0

A series circuit must be drawn in a schematic style.

Answer 0

False; There are many acceptable drawing styles that can be used to solve the series circuits including, schematic, ladder and wiring styles.

Question 1

How many paths does it does a series circuit have to flow through?

Answer 1

One path

Question 2

What is the equation you would use to calculate the total resistance of a series circuit containing four resistors?

Answer 2

Rt = R1 + R2 + R3 + R4

Question 3

Three resistors are connected in series circuit. Calculate the value of resistors R3 if:

• R1 is 20 omhs
• R2 is 37 omhs and
• the total resistance of the series circuit is 80 omhs

Answer 3

The total resistance in the series circuit is:
Rt = R1 + R2 + R3
80 omhs = 20 omhs + 37 omhs + R3
R3 = 80 omhs - 20 omhs - 37 omhs
R3 = 23 omhs

Question 4

State Kirchhoff’s Law

Answer 4

Kirchhoff’s Voltage Law says that the algebraic sum of all voltages in a closed circuit is zero. This means that:

• The sum of the voltage rises plus the sum of the voltage drops must equal zero and
• The applied voltage equals the sum of the voltage drops

Question 5

A series circuit has how many path(s) for the current to flow.

Answer 5

One
