CET ELEC.7 Parallel Circuits
What characterizes a parallel circuit? - correct answer ✔It has more than one
path for current flow.


Why are circuits in homes connected in parallel? - correct answer ✔Because
each device receives the same voltage.


State three rules concerning parallel circuits. - correct answer ✔1. The total
current flow in the circuit is the sum of the currents through all of the
branches; this is known as current cells


2. The voltage drop across any branch of a parallel circuit is the same as the
applied voltage.


3. The total resistance of a parallel circuit is always less than the lowest value
resistor, or branch in the circuit.


A parallel circuit contains four branches. One branch has a current flow of 0.8
A, another has a current flow of 1.2 A, the third has a current flow of 0.25 A,
and the fourth has a current flow of 1.5 A. What is the total current flow in the
circuit? - correct answer ✔3.75 A


Four resistors having a value of 100 Ω each are connected in parallel. What is
the total resistance of the circuit? - correct answer ✔25 Ω


A parallel circuit has three branches. An ammeter is connected in series with
the output of the power supply and indicates a total flow of 2.8 A. If Branch 1
has a current flow of 0.9 A and Branch 2 has a current flow of 1.05 A, what is
the current flow through Branch 3? - correct answer ✔0.85 A
