Q25 of 40 Page 92

If the resistance R1 is increased (Fig.14.10), how will the readings of the ammeter and voltmeter change?



Applying KVL in the loop shown.




So, iB is inversely proportional to R1.


Also,


This will reduce the emitter reading. Also the potential across R2 is R2ic. Hence the voltmeter reading also decreases.
