P = I^2 x R (Power = current^2 x resistance) (5, 1) 3. ε = V+v (e.m.f = terminal p.d. + lost volts) (3) 5. ΔQ = IΔt (Charge(C) = current(A) x time) (6) 6. E = I^2Rt (current^2 x resistance x time) (6, 1) 8. R = V/I (resistance (ohms) = p.d./current) (10) 10. E = VIt (p.d. x current x time) (6, 1) Down 2. V = ε - Ir (terminal p.d. = e.m.f. - (current x internal resistance) (8, 2) 3. E = (V^2/R)t ((p.d.^2/resistance) x time) (6, 1) 4. λ = h/mv (de Broglie wavelength = Planck's constant/mass x velocity) (2, 7, 10) 9. ε = E/Q (electromotive force = electrical energy/charge) (3)
