After enjoying the song, they have to work on the following:
Complete the sentences by the suitable word.
a) In parallel circuits, the 2 laws are …………… of currents
and ………………. of voltages.
b) In series circuit, the 2 laws are …………… of currents and
………………. of voltages.
c) I = I1 = I2 = I3 and UG = U1 + U2 + U3 in …………… circuits.
d) I = I1 + I2 + I3 and UG = U1 = U2 = U3 in …………… circuits.
After finishing this work, listen again to podcast to make the
correction.
Third:
Give the following exercise as H.W. or a group work to solve.
They can solve it using the podcast as a reference.
In this exercise all lamps are identical
