1

The voltage across all branches of a Parallel circuit is the same because ?

All branches are connected across the voltage source

2

You can find the total current for parallel circuit by

simply adding the individual currents. IT= I1 + I2 + I3 + ....

3

In a series circuit, current will be the same throughout the circuit because ?

There is only one path for current to follow

4

In a series circuit , the current flow will be ?

Will be the same in all parts of the circuit

5

To find the total resistance in a series circuit ,

just add the individual resistance : Rt = R1+ R2+ R3

6

If two or more resistors or consuming devices are placed one after the other

Series circuit

7

A single path for electrons to flow is called

A closed or complete circuit

8

What happens if a circuit is broken as in wire (conductor) being disconnected ?

No current would flow (open circuit)

9

Open circuit =

infinite circuit resistance

10

Circuits are?

The pathway along which electrons move to produce various effects

11

A short circuit means that

There is a path of low or lower resistance to electron flow that is frequently unintended or accidental

12

Fuses are placed in

In series with the consuming devices

13

Fuses are used to prevent

the damaged done by excess current flowing in a circuit

14

Ground

zero voltage point of the system

15

Earth Ground

where all of the wiring grounds are connected to. Is used to guide electrical current away from panels and equipment.

16

Chassis

the frame of the equipment where the ground wire in an electrical cord us connected to.

17

A Short circuit Is something to be avoided because it can

It can cause a fire or overheating

18

A loose connection can cause

An Open circuit

19

The total resistance (RT) of a parallel circuit cannot be found

by adding the resistors values
Instead use the 2nd function x-1 calc values **do the same to the answer**

20

Current in a parallel circuit depends on ?

The resistance of the branch

21

A load resistance is inversely proportional to current because ?

If a loads resistance were to decrease , the current flowing in the circuit would increase

22

Power is defined as

The rate at which work is done
P = I x E

23

Total power consumed in the circuit is equal to the

sum of the individual power consumptions (PT = Pl + P2 + P3... + PN).

24

Any complex combination circuit can be reduced to

an equivalent resistance or simple circuit.

25

After the total resistance of a combination circuit is reduced to a simple series or parallel circuit, the source voltage

can be applied and the total current value determined.

26

Kirchhoff's current law states that the total current entering a junction or parallel circuit is

equal to the current leaving that junction or parallel circuit.

27

In a parallel circuit, the voltage is

equal through the circuit ((ET = El = E2 = E3... = EN).

28

The total resistance in a series circuit is equal to

The sum of all the resistance values in the circuit (RT = Rl + R2 + R3... + RN).

29

The source voltage in a series circuit is equal to

the sum of the voltage drops (ET = El + E2 + E3... + EN).

30

The device used to produce electricity by heat is the

Thermocouple
