Answer:
- The charge on the plates will increase with time
- The potential difference across the capacitor starts with zero and then increases gradually to a maximum value
- The current through the circuit starts high and then drops exponentially
Explanation:
<u>Case : An uncharged capacitor is connected to a resistor and a battery in a closed circuit.</u>
- The charge on the plates will increase with time
applying this equation : Q =
as the value of (t) increases the value of Q increases i.e. charge on the plates
- The potential difference across the capacitor starts with zero and then increases gradually to a maximum value
applying this equation : V = ![V_{0} [ 1 - e^{\frac{-t}{RC} } ]](https://tex.z-dn.net/?f=V_%7B0%7D%20%20%5B%201%20-%20e%5E%7B%5Cfrac%7B-t%7D%7BRC%7D%20%7D%20%5D)
- The current through the circuit starts high and then drops exponentially
current : I =

Answer:
displacement power factor is 0.959087
Explanation:
given data
THD = 88%
true power factor = 0.72
solution
we get here total harmonic distribution THD is express as here
THD =
..............1
her g is distortion factor
so put here value and we will get g that is
0.88² =
solve it we get
g = 0.750714
and
displacement power factor is express as
DPF =
.................2
put here value and we will get
DPF =
DPF = 0.959087
