There are loads of students suffering in University who would love to have teachers like you.

I applied for over 100 university jobs like 5 years and never heard back from them. I decided to start Physics Ninja.

@andriykopiychuk3307 2 жыл бұрын

So, why then, when I connected 10K 0.25W resistor to the 12V battery it got hot enough to burn my finger? According to the calculations: 12v/10000 Ohms = 0.006Amps; And then 0.006A*12V = 0.072Watts. While resistor tested was 0.25W - way more then 0.072Watts required. Why is it getting melting hot?

@zorack4961 5 жыл бұрын

Shouldnt the P.D across the 1ohm resistor and the 3 ohm resistor be 20V , as it is parallel to the battery?

@PhysicsNinja 5 жыл бұрын

Not in this case because there is another resistor in the same branch as the battery. The potential drop across each branch must be equal.

what do we do when we have 3 resistance in a parallel circuit instead of 2? :(

@aliciaroberts3965 2 жыл бұрын

it adds the same! just sum them all up inversely for parallel resistances. so for 3 resistors it would be (R1+R2+R3)/R1R2R3 just make sure to apply the directions correctly based on the direction of the current by Ohms and Kirchhoff's laws :))

Nice explanation but why 1i2 = 3i3 ?? i didn’t understand this point💔

@PhysicsNinja 5 жыл бұрын

SßS ßS the voltage across each branch in a parallel circuit must be the same, so across the center branch the voltage drop is i2 * 1 and across the last branch it’s i3*3. each of the terms is given by R*I.

You go through the smallest steps which isn't necessarily good. At this stage students can obviously understand the calculation steps while you just go through the conceptual steps. It was hardly a 2 or max 3 minutes question that you explained in 13 minutes. You explain quite clearly though.

Needlessly leaving shit as fractions? Why? Nobody does this? You're own personal preference? Seriously dude, unreal

@PhysicsNinja Жыл бұрын

Lol, no need to get all worked up over fractions. It was to show that the power dissipated was exactly the same as the power supplied, no rounding errors.
