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).
