1)electric current is the flow of charges from one point to another.
2)electrons .
3)ampere (A).
4)electric circuit is something which consists of battery or cell attached with some other component like bulb or resistance or ammeter or voltmeter.
5)cell or battery.
6)means the difference in electric potential b/w the two terminal of battery is 1V.
7)length directly proportional
area inversely proportional
nature of resistance
temperature of surrounding directly proportional .
all the remaining question sol. will be there in ur TB.
24 )6and 12 in parallel effective is 4ohms. 5 in series with eff. 4 ohms,so the effective now is 9ohms .4 and 8 ohms are in paralel so eff. is 8/3. now eff. 9ohms and eff. 8/3ohms in series so the resultant of all these is 35/3 or 11.67ohms

Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Hope it helps you ✌
