3 352 452 6 V 50 r=0.5Ω (SC/GCE) Fig. 4.31 The diagram above (fig. 4.31) shows a 6 V battery of internal resistance 0.5 ohm connected to three resistors of values 3 ohm, 4 ohm, and 5 ohm as shown. Calculate the current in each resistor, the p.d. across the 3 ohm resistor, and across the parallel resistors. ​
