< PreviousMedan Listrik, Potensial Listrik, dan Kapasitor101Setelah mempelajari bab ini, Anda tentu menjadipaham tentang listrik statis, medan listrik, potensial listrik,energi potensial listrik, kapasitor dan jenis-jenisnya, sertabagaimana cara kapasitor bekerja. Dari semua materipada bab ini, bagian mana yang menurut Anda sulit untukdipahami? Coba Anda diskusikan dengan teman atauguru Fisika Anda.RefleksiPemasangan kapasitor pada sakelar-sakelar listrikyang memiliki daya tinggi dapat menghilangkanterjadinya percikan bunga api. Pemanfaatan ini bergunasekali untuk keamanan. Coba Anda tuliskan manfaat lainpenggunaan kapasitor.9&8&3.786.0>6?:>3E=<2?36BEA2Peta Konsep4@?D@9A6BC2>22?<E2D>652??I2(652?':CDB:<>6?I:>A2?>6?I6323<2?652+@D6?C:2=':CDB:<. ?6B8:+@D6?C:2=':CDB:<,-.(E2D2?.:D:<(E2D2?.6B5:CDB:3EC:M@=2&@?5E<D@BM&2A2C:D@BMudah dan Aktif Belajar Fisika untuk Kelas XII102Tes Kompetensi Bab 4*6/&0&31&-5&)&'9091&8.-&3!.1.-1&-7&1&-7&89/&:&'&3;&3,5&1.3,8*5&8 @=252?>2C:?8 >2C:?8>E2D2? 52? %2B2<2?D2B3@=2252=29> %:<2<65E23@=2D6BC63ED36B2525:E52B2>2<2 2 6?6B8:A@D6?C:2=3@=2P ;@E=63 6?6B8:A@D6?C:2=3@=2P ;@E=64 ,3@=2 ,3@=25 ,3@=2,3@=2 6 6?6B8:A@D6?C:2=3@=2P ;@E=6 :<6D29E:3E2936?52D:D:<I2?836B>E2D2?I2:DE52? %:<2>6?2B:<>6?@=2<52?>6?2B:<C652?8<2?36B>E2D2??682D:7A6B?I2 D22?I2?836?2B252=29 2 >E2D2?A@C:D:7>E2D2??682D:73 >E2D2?A@C:D:7>E2D2?A@C:D:74 >E2D2??682D:7>E2D2?A@C:D:75 >E2D2??682D:7>E2D2??682D:76 >E2D2?A@C:D:7>E2D2??682D:7 -2DE2?>652?=:CDB:<52A2D5:?I2D2<2?52=2>N 2 )5 %)3 0>6 )4 )> E23E29<6A:?8C6;2;2B5:36B:>E2D2?I2?8C2>236C2B52?36B=2G2?2?;6?:C &E2D>652?=:CDB:<5:2?D2B25E2<6A:?8D6BC63EDN 2 36B32?5:?8=EBEC56?82?B2A2D>E2D2??I23 36B32?5:?8D6B32=:<56?82?B2A2D>E2D2??I24 36B32?5:?8D6B32=:<56?82?<E25B2D;2B2<2?D2B<6A:?85 36B32?5:?8=EBEC56?82?;2B2<<65E2<6A:?86 2B29?I2>6?E;E<6<6A:?8I2?836B>E2D2?A@C:D:7 -63E296=6<DB@?52=2>CE2DE>652?=:CDB:<D:52<>6?8 2=2>:82I2;:<26=6<DB@?D6BC63ED 2 36B86B2<52=2>2B29D682<=EBECD6B9252A>652?=:CDB:<3 36B86B2<C6;2;2B56?82?2B29>652?=:CDB:<4 36B86B2<56?82?2B29C6>32B2?85 36B86B2<>6=:?8<2B6 D:52<36B86B2< E2>E2D2?D:D:<C6;6?:C52?C2>236C2B-- 36B252A252;2B2< 4>C2DEC2>2=2:? %:<2'P )>36C2B82I2D@=2<I2?85:2=2>:<65E2>E2D2?D6BC63ED252=29 2 )3 P )4 P O)5 P O)6 P ) +6B92D:<2?82>32B36B:<ED +B@D@?I2?836B86B2<52B:<6A:?8<6<6A:?8 C6A6BD:D2>A2<A25282>32BD6BC63ED>6>:=:<:<646A2D2?P >C %:<2;2B2<2?D2B2<6A:?852=2>F2<E> 4>>2CC2AB@D@?

tersusun darimagnet-magnet elementer. Tiapmagnet tersebut terhubung denganotak melalui saraf. Sensor tersebutdapat menentukan posisi arahmelintang sepanjang magnet Bumi,selain itu juga dapat menentukanketinggian posisinya dari permukaanBumi.Pigeons have recently been found tohave multiple-domain magnetitemagnets within their skulls. That areconnected with a large number ofnerves to the pigeon’s brain. Pigeonshave a magnetic sense, and not onlycan they discern longitudinaldirections along the earth’s magneticfield, but they can also detect latitudeby the dip of the earth’s field.Informasiuntuk AndaInformation for YouSumber: Conceptual Physics, 1998Aktivitas Fisika 5.1Medan Magnetik di Sekitar Kawat BerarusTujuan PercobaanMengamati medan magnetik yang disebabkan oleh kawat berarus listrik.Alat-alat Percobaan1.Sebuah baterai4.Kawat penghantar2.Kabel5.Kompas kecil3.Sebuah saklarMudah dan Aktif Belajar Fisika untuk Kelas XII108012Gambar 5.7(a) Kaidah tangan kanan; (b) Jika arusmenuju pengamat, arah medanmagnetik berputar ke kiri; (c)Jika arah arus menjauhipengamat, arah medanmagnetik berputar ke kanan.%012%$?4@B0<0:0;8<4<?C1;8:0A8:0=?4=4<C0==F0B4=B0=6?4=60@C7:C0B<430=<06=4B8:38A4:8B0@:0E0B14@0@CA&0300E0;=F0A420@0B830:A4=609080<4;4B0::0=90@C<:><?0A380B0A:0E0B?0=90=6F0=614@0@CA*4@=F0B090@C<:><?0AB4@A41CB<4=60;0<8?4=F8<?0=60=&4@8AB8E0?4=F8<?0=60=90@C<:><?0A30?0B=30?4@70B8:0=<4;0;C8!,"!0 8:0B830:B4@30?0B0@CAF0=6<4=60;8@<4;0;C8A41C07?4=670=B0@90@C<:><?0AB4B0??030?>A8A8A48<10=6F08BCCB0@0A4;0B0=A4?4@B8!,"!0!!4B8:00@CA<4=60;8@30@80@07CB0@090@C<:><?0A0:0=<4=F8<?0=6:4:0=0=A4?4@B8!,"!0"30=:4B8:00@CA<4=60;8@30@80@07A4;0B0=90@C<:><?0A0:0=<4=F8<?0=6:4:8@8A4?4@B8!,"!0#0@8?4@2>100=F0=638;0:C:0==F0%012%$<4=F0B0:0=107E038A4:8B0@?4=670=B0@14@0@CAB4@30?0B<430=<06=4B8:F0=60@07=F014@60=BC=6:4?0300@070@CA;8AB@8:F0=6<4=60;8@<4;0;C8?4=670=B0@B4@A41CB+=BC:<4=4=BC:0=0@070@CA;8AB@8:30=60@8A60@8A<430=<06=4B8:=3030?0B<4=66C=0:0=0BC@0=B0=60=:0=0= 8:00@CA;8AB@8:380;8@:0=?030:0E0B;C@CAF0=6<4=4<1CAB460:;C@CA?0301830=6F0=6B4;0738B01C@8A4@1C:14A8A4@1C:A4@1C:14A80:0=<4=C=9C::0=?>;060@8A60@8A<430=<06=4B8:F0=614@14=BC:;8=6:0@0=A4?CA0BA4?4@B838BC=9C::0=?030!,"!0 @0760@8A60@8A60F0<06=4B8:38A4:8B0@?4=670=B0@14@0@CA30?0B38B4=BC:0=34=60=:08307B0=60=:0=0=A4?4@B8!,"!014@8:CBGambar 5.5(a) Penghantar tidak dilalui arus listrik;(b) Penghantar dialiri arus listrikdari utara; (c) Penghantar dialiriarus listrik dari arah selatan.Perhatikan arah simpanganjarumnya.Gambar 5.6Pola garis medan magnetik yangdibentuk oleh serbuk besi di sekitarkawat lurus berarus listrik.Sumber: Conceptual Physics, 1998SUUUUUUSSSSSBB012BBLangkah-langkah Percobaan1.Susunlah peralatan sehingga terlihat seperti Gambar (a).
