1.An ammeter of resistance 0.16 ohm is shunted with a resistance of 0.04 ohm which gives a reading of 8 A. The current in the main circuits is

2.The sequence of bands on carbon resistor is brown, black, brown and gold, the value of resistance is either

3.A voltmeter 100 V range is of 9000 ohm resistance and another voltmeter of range 80 V has a resistance of 11000 ohms. This combination is connected across 120 V. The reading of voltmeter of 100 V range will be

4.The e.m.f. of a cell is E when connected across a resistor R, the P.D. between the terminals is V. The internal resistance of the cell is given by

5.With a cell of e. m. f. 1.5 V the balancing point is obtained at a distance of 60 cm from one end of a potentiometer wire. Find the p.d. between the two ends of the wire, if its total length is 1 m.
