Emf and ohm law experiments in the lab.


I was a little afraid that I would not see the day in Convent Sentul where every student can set up their own electrical circuit and take their personal individual readings of volmeter and ammeter without being aided by any one.

But today was the day the girls embarked on doing their electrical circuit for the first time in their life! Delightfully all 33 girls started doing their own experiment about 11.20 am and all completedthe experiment succesfully by 12.15 noon.

Sharmilla deep in concentration with her circuit.

Of course the preparations towards today's experiments were not as easy.


First the lab assistants had to be trained - thank God I managed to get Ibrahim my very competent ex- lab assistant from SMK Padang Tembak to come over to train our lab assitants for two days.

Now finally they managed to identify and locate long lost equipment such as the long rheostat etc etc, and prepare and repair whatever faulty equipment to make 15 sets of electrical circuits.


rb stands for red button and bb stands for black button and red lines indicate red wires connevted to the positive terminal of the battery and black lines represent black wires connected to the negative terminal of the battery.


I am happy to report the girls enjoyed the experiments and the first batch girls were able to confidently teach the 2nd batch girls to do the experiments.

There were some students I had to test to make they could do all on their own without any assistance and yes! Harkiren did it all by herself! Hallelujah! See the smile playing on Harkiren's lips as she sets up her own circuit.




















Darshna sets up her own circuit under the watchful eyes of her two friends.





















Rachael and Rinnisha grinning as they read their ammeters and voltmeters.







































And lastly now to test you. What's the reading on the ammeter?
