Current average I_avg {Ans: = change in charge over change in time = change in Q/change in t}Potential energy PE_E *PE_E can also be denoted as U_E {Ans: = charge times voltage = k times magnitude of charge 1 times magnitude charge 2 all over their radius = q•V = (k•q_1•q_2)/r *k can also be writing as one over the entirety of 4 times Pi times vacuum permittivity k = 1/(4•Pi•E_o) * voltage is also called electric potential or potential difference}Capacitance sub p C_p {Ans: = the sum starting at i of capacitance sub i = sigma_i(C_i)}Force of a particle due to magnetic field F_B {Ans: = magnetic field times current times length times the sine of theta = B•I•l•sin(theta)}Right hand rule #1 {Ans: = extend the right hand so the fingers point along the direction of the magnetic field (B) and the thumb in the direction along the velocity (v) of the charge ~OR~ the current. The palm of the hand then faces in the direction of the magnetic force (F_B) that acts on a positive charge * use back of hand for negative charges * for a charged particle going through North and
