Question

guys plzz solve this question of electricity... ​

Answer 1

Explanation:

ANSWER:-

NO, There is no change in Ammeter Reading.

REASON:-

• There is no change because the Ammeter 1 has also the same resistance 4 ohm.
• Now in second Ammeter also resistance is 4 ohm
• DERIVATION

GIVEN:-

Parallel Resistance 8 ohm each.

We know for parallel resistance,

$\frac{1}{x} = \frac{1}{x1} + \frac{1}{x2}$

If x is equivalent resistance.

So,

$\frac{1}{x} = \frac{1}{8} + \frac{1}{8}$

$\frac{1}{x} = \frac{2}{8}$

$x = 4 \Omega$

As both of them have equal resistance, the Ammeter will show the same reading.

Note:-

• Reciprocal the value when calculating Parallel combinations
