4. A battery of e.m.f. 15 V and internal resistance3 ohm is connected to two resistors of resistances3 ohm and 6 ohm in series. Find(a) the current through the battery(b) the p.d. between the terminals of the batteryilsAns. (a) 1-25 A (b) 11-25 V

Answer»

The current through the battery is = (15)/(3+3+6) = 1.25A

b) P.D between the terminal of the battery is = 1.25*(9) = 11.25 v
