[問題] 普物裡的電學題目
做普物考古題碰到的題目
1. A series RCL circuit has a capacitance of 1.2 mF and an inductance of
2.0 mH. What is the resonance frequency of the circuit?
(a)325Hz (b) 1250Hz(c) 2580Hz (d) 3250Hz
f = 1 / (2π * 根號(LC)) 公式好像是這樣
不過我代值進去後 答案竟然都不一樣XD
2. A series circuit with an inductance of 15 mH, a capacitance of 35 uF and
a resistance of 5 ohm contain a sinusoidal source of emf with a frequency
of 500 Hz. The frequency with which the charge on the capactor oscillates
is (a) less than 500 Hz (b) 500 Hz (c) between 500 Hz and 1.4kHz
(d)greater than 1.4 kHz
請會的大大不吝指導
