#### Storyboard Text

• Hello everyone!Welcome to the 2nd Physics session of 2020
• Steve Nye,The science guy !!
• ELECTRICITY
• Good Morning all !! Today we are gonna watch videos by Mr.Nye on Electricity!!
• YAY!!!!!
• WLC
• OHM'S Law : Ohm's law states that the P.D (V) across the ends of a metallic wire inan electric circuit is directly proportional to the current (I) through it , at a constanttemperature. V = IR 1 Ohm = 1V/1A
• Hmm...!Interesting !!
• WLC.
• Factors: Affecting ResistanceR = P l/AP (Rho) = C of proportionalityl= Length & A = area of C.SNature of material & temperature
• WLC.
• Resistors:Parallel : Components are connected across each other forming 2 sets of electrically common points.1/Rp= 1/R1 + 1/R2Series ; Components are connected end toend forming single path for current flow.Rs = R1 +R2
• Miss why is mr.Nye so funny ?
• Don't irritate !!
• WLC.
• Yep !
• That's all for today !!Kids ! Don't forget to memorise the symbols for circuit diagram. Adios !!
• O.K !!Let's get going..
• Do you realize I'm still in class
