  1. It is only in an ac circuit that energy can be STEADILY STORED in an inductor. In a dc circuit, only transient...the term (Vb.I), which is the energy stored in the inductor.

  2. (a) Energy stored in the 20 uF capacitor = (1/2).(20x10^-6).(180^2...each capacitor = 0.018/2 C = 0.009 C (d) Energy stored in each capacitor = (1/2).(0.009^2)/(20x10^-6) J...

  3. 最緊要都係睇下邊個係constant 如果capacitance係constant就用有c果2條 如果係voltage 係constant 就用v果條 2008-01-24 01:40:54 補充: 加埋我個...

  4. ...sure we have the power to do it all. There are two types of energy -- stored (potential) energy and working (kinetic) energy . For example, the food you eat...

  5. 弓(bow)所貯的能量屬於彈性勢能。主要是因為弓及弦的變形而產生的能量。由於它受力和形變的情況比較複雜,所以比較難計算。但可以用實驗的方法測量。 用的方法可以用不同的砝碼吊在弦之下,量度砝碼的質量(重量)和弓被拉下距離的關係,將這些數據繪成 mg – x (砝碼的重量和弓被...
