Give me the ladder diagram plc for this

2. A bank of nickel-cadmium cells is used as the emergency lighting supply for a hospital. There are 100 cells connected in series and each has an A-hr rating of 120 A-hr. The bank has to be replaced, and the manufacturer is no longer supplying nickel-cadmium cells. It is decided to replace the cells with lead-acid cells. How many lead-acid cells will be required if each has an A-hr rating of 60 A-hr, and how should they be connected?

(b) The circuit in Figure Q2 (b) below shows a rectifier circuit where Vin is a 10kHz sine wave with an amplitude of 2Vpp and RL is 10k. (i) (iii) The componet between A and B is a PN diode, sketch and label its silicon structure and explain its characteristics. Sketch the waveforms you would see at A and B and explain or sketch how you would connect your scope probes to measure them. Label your sketches clearly showing values and axis details. Comment on any similarities or differences between the waveforms at A and B.
