K.C.S.E Physics Q & A - MODEL 2013PP2QN019
(a) Figure 14 shows an E shaped steel block being magnetized by a current through two coils in series.
On the figure, indicate
(i) the north and south poles of the resulting magnet
(ii) the complete magnetic field pattern between the poles.
(b) Figure 15 shows the permanent magnet made in part (a) above.
A coil wound loosely on the middle limb is connected in series with a low voltage a.c. and a switch. State and explain the observation made on the coil when the switch is closed.
(c) In a simple cell, the zinc plate gets negatively charged and the copper plate gets positively charged.
(i) Name the electrolyte in the cell.
(ii) Explain how:
(I) Zinc gets negatively charged.
(II) Copper gets positively charged
(iii) State what constitutes the current when a wire is used to connect the zinc plate and the copper plate externally.
What is the difference between electromotive force and terminal voltage?
It was awesome researching scientific findings using Atika
