B) A series type ohmmeter, designed to operate with a 9-V battery, the meter movement has an internal resistance of 2000 ohm and requires a current of 100 µA for full scale deflection. The value of R1 is 49KQ. a) Draw a typical circuit for this ohmmeter. b) Assuming the battery voltage has fallen to 8.8 V, calculate the value of R2 required to zero the meter. c) Under the conditions mentioned in part a, an unknown resistor is connected to the meter causing a 60 per cent meter deflection. Calculate the value of the unknown resistance.

Question 1 Consider the adjacent circuit diagram of three different rectifier topologies connected to an 373 Volt three-phase AC system. Assume a load resistance of 36Ω in ALL instances with NO losses in the rest of the circuit. Observe the connections to the AC supply and determine the parameters for, Rectifier B: 1.1) the maximum voltage across the load and the dc load voltage and the r.m.s. load voltage. 1.2) the rectification efficiency and the r.m.s. current rating of the diodes. 1.3) the conduction period of a single diode and the PIV rating of the diodes.
