In the circuit given in the figure, the limiting error in the power dissipation ‘I2R’ in the resistor R is:
-
- 1·2%
- 5·2%
- 10·2%
- 25·2%
- 1·2%
Correct Option: C
From given figure
We know that power dissipation is given by relation
P=I2R
or
| = 2 | + | |||
| P | I | R |
Therefore, the limiting error in power
or
| = 2 × 5 + 0.2 | |
| P |
or
| = 10.2 % | |
| P |
