$14.6. Define resistance and its units.$

$13.10 Ten resistances of different value are connected in parallel. If the p.d.across one of them is 5 \mathrm{~V} . what is the p.d. across the remalning nine resistors?$

$14.3. What do we mean by the term e.m.f? Is it really a force? Explain.$

$13.8 Find the current and power dissipated in each resistance of the circuit shown in Fig. P.13.8.Fig.P. 13.8(Ans: 0.8 \mathrm{~A} 1.4 \mathrm{~A} 2.2 \mathrm{~A} 0.64 \mathrm{~W} 1.96 \mathrm{~W} 3.92 \mathrm{~W} \& 9.68 \mathrm{~W} )$

$Example 14.1: If 0.5 Ccharge passes through a wire in 10 \mathrm{~s} then what will be the value of current flowing through the wire?$

$13.1 A certain battery is rated at 80 ampere hour. How many coulomb of charge can this battery supply$
