Voltage dtrop?

Question

A current 0f 0.5A flows through a resistance the voltage drop is 8V what is the size of the resistor

Answer 1

R=V/I
hence as you have V=8
and I=0.5 then your answer is
R= 8/0.5= 16 ohms

Answer 2

Voltage is the term utilized in engineering and daily life. the main remarkable term for voltage is ability at a element. Voltage distinction or voltage drop is the adaptation in ability between 2 factors. subsequently use the term ability rather of voltage, and ability distinction rather of voltage drop. Now you will comprehend each element. =================================== on the subject of Ohm's regulation, until ultimately one knows the concepts, be conscious that ability distinction is the reason for present day and present day is the end results of ability distinction. evaluate the two ends of a resistance, A and B. the aptitude at A (voltage of A) is 12 V and that at B (voltage of B) is likewise 12V. the aptitude distinction is 0. subsequently there is no present day by the resistance. evaluate now that the aptitude of B is 10V. the aptitude distinction is 12- 10 = 2V. we are saying that the voltage drop from A to B is 2V, (i.e., the aptitude distinction is 2V} If the resistance is two Ohm, then as in line with Ohm's regulation the present would be 1A. evaluate now that the aptitude of B is 6V. The voltage drop (ability distinction is 12 -6 = 6V. be conscious that the voltage of B is 6V and additionally the voltage drop in the time of AB is likewise 6V. yet they're different. Now the present by the resistance is 6/2 = 3A. present day is at as quickly as proportional to the voltage drop. (to no longer the voltage) ======================================... in most of the calculations we are worried basically with the voltage drop and not the incredibly voltage. subsequently it has grow to be a custom (nonetheless it relatively is no longer maximum remarkable) to synonymously use the words voltage and voltage drop. ======================================... comments: you will discover interior the most of the solutions given above, the term voltage is used. the easy answer is replace voltage by skill of ability at a element if it referes ability at a element and replace it by skill of voltage drop or by skill of ability distinction in the event that they refer drop of ability. ======================================...

Answer 3

V=IR

8v=.5a*R

R=16 Ohm
