hey since 24 hrs are over after physics exam i want to confirm 3 answers for paper1 physics:
1) Is copper ferrous, and does it get attracted to an electromagnet?
2) What was d answer for dat
a) 6v ac
b) 6v dc
c) 600v ac
d) 600v dc
3) for dat dc question whose options wer
a) generator
b) motor
c) relay
d) thermistor
copper is definitely not ferrous, the ONLY ferrous material s are COBALT, NICKEL, IRON dat is ALL
therefore, copper is not attracted to an electromagnet.
for question 2, the answer was 600V dc
for question 3, i think ur talkin about the "small dc to large dc" question
the answer is relay
