Purwokerto Purwokerto Electric Current

Purwokerto Purwokerto The 12-gauge copper wire in a typical residential building has a cross-sectional area of 3.31 x 10

• m 2 . If it carries a current of 10.0 A, what is the drift speed of the electrons? Assume that each copper atom contributes one free electron to the current. The density of copper is 8.95 g/cm 3 . molar mass of copper is 63.5 g/mol 1 mol of any substance contains Avogadro’s number of atoms (6.02 x 10 23 ) Knowing the density of copper, we can calculate the volume occupied by 63.5 g (=1 mol) of copper:

Purwokerto Purwokerto Calculate the resistance of an aluminum cylinder that has a length of 10.0 cm and a cross-sectional area of 2.00 x 10

• m 2 . Repeat the calculation for a cylinder of the same dimensions and made of glass having a resistivity of 3.0 x 10 10  m. **Hitunglah nilai hambatan silinder aluminium yang panjangnya 10 cm dan tampang lintangnya 2 x 10

m 2 . Hitung pula silinder gelas yang memiliki dimensi yang sama, yang hambat jenisnya sebesar 3 x 10 10**  m

Purwokerto Purwokerto the resistance of the aluminum cylinder for glass

Purwokerto Purwokerto A resistance thermometer, which measures temperature by measuring the change in resistance of a conductor, is made from platinum and has a resistance of 50.0  at 20.0°C. When immersed in a vessel containing melting indium, its resistance increases to 76.8 . Calculate the melting point of the indium. the temperature of the melting indium sample, is 157°C. Sebuah termometer mengukur suhu dengan cara mengukur perubahan hambatan dari sebuah penghantar yang terbuat dari platinum yang memiliki hambatan 50  pada suhu 20 C. Pada saat penghantar tersebut dimasukkan ke dalam wadah yang berisi indium cair, hambatannya meningkat menjadi 76,8 . Hitunglah titik leleh indium.
