Three dry cells each having internal resistance of 0.50 and an e.m.f of 1.5V are in series with a 1000 Blatooth, a 1000 wifi module both in parallel and a 350 GSM modules to form a simple telephone circuit. The connecting wires have a total resistance of 20 and low noise amplifier of 300. Compute the low noise amplifier voltage (4marks] b) Three ruszors, two of 4K8 boch in parallel and a third one, are connected in series. A fourth resistor of 4M5 and fifth of twice the value of the third resistor together in series are connected in parallel with this circuit. The equivalent resistance of all the five resistors is given by 3KS L Calculate the value of the third and fith resistors. H. If a banery with eaf of 20V is connected to this final circuit, calculate the curcax through the fifth resistor Repeat for capacitors. [6marks]
