If the resistance R 1 is increased (Fig.14.10), how will the readings of the ammeter and voltmeter change?

Question

Philoid · Accepted Answer

Applying KVL in the loop shown.

So, i_B is inversely proportional to R₁.

Also,

This will reduce the emitter reading. Also the potential across R₂ is R₂i_c. Hence the voltmeter reading also decreases.
