1. A lightning bolt with 8 kA strikes an object for 15 s.
How much charge is deposited on the object?
2. A rechargeable flashlight battery is capable of delivering 85 mA for about 12 h. How much
charge can it release at that rate? If its terminal voltage is1.2 V, how much energy can the
battery deliver?
3. If the current flowing through an element is given by
Plot the charge current relate graphs at a given interval.
4. Determine the current flowing through an element if the charge flow is given by function below
@ t=0.5sec.
a/ Q(t)=(4t+3)mc
b/ Q(t) =(4t7+4t6+3)mc
c/ Q(t)=(3tsin(4t))mc
d/ Q(t) =23e2tmc
5.Calculate the power supplied or absorbed by each element and apply passive sign convection and
check condition of
Psupplied=Pabsorbed
6.Compute the power absorbed or supplied by each component of the
circuit given below.

7.Find power absorbed or supplied through given element below.
8.A telephone wire has a current of1015 A flowing through it. How long does it take for a charge of
15 C to pass through the wire?
9. fig.below shows a circuit with five elements. If p1=205w,p2=60w,p4=45w and p5=30w calculate the
power received or delivered by element 3.
10. Calculate the power supplied or absorbed by each element in fig below and also check for passive
sign convection that is Psupplied=Pabsorbed
