K.C.S.E Physics Q & A - MODEL 2017PP2QN17
(a) Figure 8 shows a conductor AB connected to a galvanometer and placed between two permanent magnets.
(i) Conductor AB is moved perpendicular to the magnetic field.
State and explain the observation made on the galvanometer.
(ii) State the effect of moving the conductor faster.
(b) A transformer is used to step down 240V to 12 V for use in an electric appliance operating at 0.5 A. If the primary coil has 600 turns, determine the;
(i) number of turns ¡n the secondary coil,
(ii) current in the primary coil.
