  • Formulas:

    • U = U1 + U2 + … + Un

    • P = UI

    • I = \frac{\varepsilon}{R+r}

    • Q = I^2Rt

    • R = p \frac{l}{s}

    • R = R_0 (1 + at)

    • I = \frac{\varepsilon}{R+r}

    • U = \frac{neS}{I}

  • Page 4: Conditions for the Existence of Electric Current

    • Electric current is the directed (ordered) movement of particles having an electric charge

    • The two necessary conditions for the emergence and maintenance of electric current are:

    • The presence of free charged particles, which act as current carriers
