3 91 and 92 = two electric charges r= distance between two electric charges F = Force 2. V=W:W=VxQ:Q=W = V p.d. W = work done, Q = Quantity of charge transferred 3. V=RxI:R=Yil-K pd Resistance, /= current. 4. R=PXl:p=RxA R = Resistance; = length; A = Area of cross section; p = rho, a constant known as resistivity 5. Series combination R=R1+R2+R3.....+R 6. Parallel combination 11/11/19 For equal resistances Rs = nR (For series connection) RP=R (For parallel connection) Rs - n Rp Rs = Effective resistance in series Rp = Effective resistance in parallel n = number of resistors R = Resistance of each resistor 7. : Power = Time consumed 8. /=Vx/xt Power potential difference x current x time = 9. P=Vxl:Power = potential difference x current 10. P=12xR ; Power = (current)2. resistance 11. : Power = (potential resistance difference)² 12. Electric energy = Pxt electric energy = power time
