the voltage current characteristics curve of a non ohmic device is V = 4 I Square as shown in figure. then what is the resistance of device when the current of 1 ampere
1) 4 ohm
2) 8 ohm
3) 2 Ohm
4) 6 Ohm
Answers
Answer:
2) 8ohm
Explanation:
R = dv / dI
here, V =4i^2
dv / dI = 4×2×i
= 8i
current i = 1A
= 8×1
= 8ohm
Answer :
OPTION 1) 4 ohm.
Given :
Here the given informations are
Current (I) = 1 A
Voltage (v) = 4 I²
To find :
Resistance (R)
Explanation :
We can use same method of ohmic conductors to determine resistance in non ohmic conductors also. After plotting the graph, mark out the point and find respective current and voltage for that point. And use the formula given by,
R= V/I
= 4I²/I
= 4I
= 4×1
= 4 ohm.
For a non ohmic resistor, the ratio V/I is not necessarily the same as the slope of the curve.Since resistance is defined via ohm's law, the resistance is the ratio, not the slop.
