12. P = V x I

As Jungkook walked towards Jimin, the entire class looked at him and assumed something was going to go wrong, but they met with disappointment. "Uh, Jimin?" Jungkook called as Jimin was seated with his left buttock placed on the desk and talking to Hoseok. 

Hoseok smiled at Jungkook and turned Jimin around by launching his legs to the other side of the table. Jimin saw Jungkook in a yellow hoodie with black loose denim pants and yellow sneakers. "T-thank you for letting me borrow the notebook and a pen yesterday." The younger said, extending a big glossy hardcover notebook and an expensive pen towards the senior. 

Jimin looked at it and then his gaze moved up to see Jungkook's face. He could tell the boy was nervous with the way his eyes kept wavering everywhere and he nibbled on his lips. Hoseok gripped Jimin's shoulder tightly to sign him to behave. He accepted the notebook and pen from Jungkook's hands and carelessly flopped them on the desk. "No problem."

Jungkook flipped as he began to walk ahead and then realized he was sitting on the back seat, so he turned around and Jimin kept staring at him for the entirety of his act. The bell rang and the Physics teacher walked in.

Everyone settled down when the teacher wrote the topic of the day on the whiteboard. "We are going to study about Power today. Can anyone tell me which law is it based on?" The teacher asked and looked at everyone hiding behind the books, except Jimin, who stared at him, Jungkook, who looked excited, and last but not the least, Yoongi, who seemed like he didn't listen to anything. 

"Anyone?" The teacher made strong eye contact with the three boys and saw Jungkook sticking his hand up zestily. 

"Yes, Jungkook." The teacher pointed the tip of his marker towards the boy.

"It's based on Ohm's law. Voltage is proportional to current. If voltage increases, the current also increases." Jungkook replied proudly.

The teacher grinned ear to ear. "Well done." He then turned around to write the equation on the board, P=VxI. 

By then, everyone started to note everything on their notebooks. "What's 'I' here?" The teacher mumbled with his back towards the class as he wrote on the board.

The only one who kept answering was Jungkook. Jimin annoyingly looked at him and rolled his eyes, not able to control his inner sass. "Yo, Einstein!" He bellowed. "Let us also listen to what the teacher has to say."

"Jimin!" The teacher warned the boy who only looked at him. Shaking his head, he got back to the whiteboard, not wanting to get into whatever the rivals had got going.

Jungkook looked at Jimin, perplexed, and then stopped talking altogether. The class was silent except for the teacher talking.

"So, in case of the transformers, if the power increases to the primary side, the secondary side will also increase as per Ohm's law." The teacher was depicting an example with the help of a diagram and the equations. 

"Actually that's not correct," Jimin spoke for the second time since the class started. 

"That is wrong." Jungkook blurted out together with Jimin. 

The whole class whipped their heads to the two, including the teacher. "What is it, Jimin and Jungkook?"

"It depends on how you increase the parameters, e.g. if you increase the voltage by keeping the power of the source constant, then the current would decrease when the voltage increases." The youngest answered. 

"Yeah, same." Jimin pointed towards Jungkook and Hoseok burst out laughing. 

"What's so funny, Hoseok?" Earlier, the teacher didn't seem offended by the students correcting him but now.
