frequency, power and energy (work). Electric current is

measured in Ampers (A) Frequency Is messured in Herz

Power Is messured in Watts (W)

Energy is messured in Joules (J)

2. What

is the main difference between Engineering notation and Scientific notation ?

Give examples. Enginering notation oly allows three digits to the left of the

decimal, it has to be written in multiple of three.

3. What

is the difference between AC and DC voltages? Give examples.

AC is alternating current that can

shange directions. DC only flows in one direction.

6. A mass of 1000kg is dropped through

a height of 16m in 22s. What is

(a) The work done 160000 J =160KJ Power*work/time =160000/22

= 7272.73J/s =7.272KJ/s

(b) The power developed?

10x60x6=3600Wh = 36

kWh

(c) 100×4= 4 = 400W= 0.4 Wh

(d) 1000x3x3=9000=9 WH Work=Power X Time =

3600×90+400×90+9000×30=630000J = 630kJ

Results Comment;

There was a small

variation between the recistans results.. This variation could have been caused

by the rounding off numbers. This method might not lso not work for those who

are colorblind.

Conclusion;

To Read the First

Band, You have to know the Color-Code which we used during the experiment.

There

might have been bad connections used in the experiment. Temperature can also

affect the results.

The sum of voltages across loop

BCDB is equivalent to 0. This equation

proves Kirchhoff’s voltage law.

Comments:

The sum of voltages across loop

ABCDA is equivalent to 0. This equation also satisfies Kirchhoff’s voltage law.

The sum of voltages across loop

ADCA is equivalent to 0. This equation also satisfies Kirchhoff’s voltage law.

Results Comments;

From our experiment, it is clear

that the sum of the currents going into

a junction is equl to the sum of currents leaving that junction.

Conclusion;

Kirchhoff’s Law shows the total

current or charge going into a junction has the same value as the charge leaving the node because it has no

were else to go. ”The sum of all current going in and out of a node equals

zero. This I shown in our experiment.

Comments;

The theoretical and the practical

value are almost the same. The slight variation in the two

values is due to the materials

used in the experiment.
