hello viewers how are you welcome to

tech study cell in this video we will

see how to identify the wattage of the

resistor as you know the wattage is an

important specification of a register so

how to identify it the resistance can be

one foot word up what 1 watt to work 3

watt and above how to identify now for

one foot what the resistance or register

will look like this

again for half what it will look like

this slightly increased in size for one

word or two what this is and this is 40

watt as we can see that in one fourth

word the size is less but in half what

the size is greater than the one foot

one again the volume or size increased

in one word again in toward baalam and

size is increased again introvert also

the size is increased from the to watt

as the what is increase the size is also

increase of the register the resistance

value of this to register are same 100

ohm we can measure it by color-coding

but there what is the different as we

can see their size are different so this

is for tort and this is for one water

and the size increase as for Harvard the

power dissipation will be larger so the

size and volume is also increased with

the word now another fixed type of

resistor used for higher voltage the

we are want register now this is the

wire bound register having two terminal

and we can measure the range things of

this wire wound resistor by multimeter

now if we connect the two leads of the

multimeter in this two terminal the

value is showing to all now there is

another type of register used for higher

wattage purpose that is metal oxide

register now here this register is 14

watt as is it is written in this

register these are the carbon register

this is y around register and this is

metal oxide register this two type of

register used for higher wattage purpose

now for variable register first come to

potentiometer this is the potentiometer

and here the resistance value is 20 K as

here it is written and wattage is 1 watt

written minute and this is another

potentiometer of 10 K and the wattage

reading is one word written in the

minute

after compute lemur resistor these are

all trimmer register these are also

variable register used for lower wattage

purpose so trimmer is widely used in

electronic circuit most of the time the

wattage reading of a steamer is below

one what all the creamer is used here is

up to 1 watt we can find a wattage of a

trimmer by using the code written on the

body of a trimmer using these code we

can download a data sheet and we can

find a wattage of red trimmer and to

find the value of the resistance maximum

resistance of a trimmer we can consider

a value written on the top suppose there

is written 1 0 2 then the resistance

value should be fast to digit and last

digit will tell the number of 0 so here

is 2 so total number of 0 will be 2 so

the resistance values thousand ohm which

is 1 kilo ohm if there is written 1 0 4

again first 2 digit is and the last

digit is indicating number of zeros so

here 100 kilo ohm only streamer is hot

water

as I found it from de datos I now come

to SMT resistor which is a fixed

register this type of register is widely

used nowadays in all type of electronic

circuit follow our what is purpose and

to identify the wattage of the register

we can consider the length and width of

a SMD and you can find it from the

datasheet know what is is written on

this SMDs on the top of the SMD of three

digit is written suppose in one SMD here

on the top written one five zero which

indicates its resistance value first two

digit it's simple indicator value and

the last digit indicate the number of

zero which is zero here so resistance

will be fifteen

ohm suppose if there is written twenty

seven three on SMD then the value will

be 27 and last digit indicates the

number of zero so into 10 to the power 3

which is 27 low most of the time the

wattage of the SMD is up to one it may

be one point 1 by 16 watt 1 by 8 watt

approved one water you can find a

wattage from the datasheet this is all

about the wattage of the register both

fixed and variable thank you for

watching the video I am going to make

others useful video so for that please

subscribe our channel so that I can make

others video again thank you for

watching and please give like if you

liked the video if you need any

modification

or initiation please comment below to
