Question
the time constant maximum charge the time to have a charge of 10 micro coulombs An electron travels at 1.5 times 10^n 6 m/s in +x axis and a magnetic field of 0 0.002T is applied in the +z direction. Calculate the force acting on the electron? What is the direction of the force? Calculate the kinetic energy of the electron Bonus: State I law of kirchoff State II law of kirchoff Explain Hall effect(3 sentences) Resistivity varies with resistance of a given material.(True or False) A capacitor is a device to store . An exists the between the plates of the capacitor.Explanation / Answer
5) F = q*v*B = 1.6*10^-19*1.5*10^6*0.002 = 4.8*10^-16 N
direction of the force positive y- direction
KE of the electron = 0.5*m*v^2 = 0.5*9.11*10^-31*(1.5*10^6)^2 = 10.24*10^-19 J
==============================================================
Ilaw of kirchoff's
the algebric sum of the currents flowing at the junction in a circuit is zero
II law of kirchoff's
the algebric sum of changes in potential around any closed loop is zero
Hall effect:
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current
Resistivity is a constant for a material
False
A capacitor is a device to store charge
An Electric filed exists between the plates of the capacitor
