Answer:
(a) 2.8 V
(b) 5.6 V
(c) 9.8 V
Explanation:
Given:
Frequency of the generator (f) = 1300 Hz)
Terminal voltage (V) =12.0 V
Resistance of resistor (R) = 14.0 Ω
Capacitance of capacitor (C) = 4.40 μF = 4.40 × 10⁻⁶ F
Inductance of the inductor (L) = 6.00 mH = 6.00 × 10⁻³ H
In order to find the voltages across each, we first need to find the reactance and impedance.
Reactance of the inductor is given as:
Reactance of the capacitor is given as:
Now, impedance is given as:
Current across the circuit is given as:
As resistor, capacitor and inductor are connected in series, the current across each of them is same and equal to total current in the circuit.
(a)
Voltage across the resistor is given as:
Therefore, the voltage across resistor is 2.8 V.
(b)
Voltage across the capacitor is given as:
Therefore, the voltage across the capacitor is 5.6 V.
(c)
Voltage across the inductor is given as:
Therefore, the voltage across the inductor is 9.8 V.
The current is defined as the amount of charge transferred through a certain point in a certain time interval:
where
I is the current
Q is the charge
is the time interval
For the lightning bolt in our problem, Q=6.0 C and
, so the average current during the event is
where
I is the current
Q is the charge
For the lightning bolt in our problem, Q=6.0 C and
