Current Electricity Charging Discharging Of Capacitors Question 227
An ammeter with internal resistance $ 90,\Omega $ reads 1.85 A when connected in a circuit containing a battery and two resistors 700 $ \Omega $ and $ 410,\Omega $ in series. Actual current will be less than 1.85 A due to the ammeter’s internal resistance.
