In the given figure an ammeter A consists of a $240Ω$ coil connected in parallel to a $10Ω$ shunt. The reading of the ammeter is $mA$

Answer:

160.00

Solution:

Req $= 140.4 + \frac{240 \times 10}{240 + 10} Req = 140.4 + \frac{2400}{250} Req. = 150Ω$ $∴ Current in ammeter = \frac{24}{150} = 160 mA$
