6 FAQs about [Capacitor and parallel resistor voltage]
Can a capacitor charge a resistor in parallel?
There will be a potential difference across the resistor in parallel to capacitor and that potential difference will be resposnsible for charging it The potential across the capacitor can't change instantaneously.
What is the final voltage between a capacitor and a resistor?
For circuits 1 and 3 the final voltage across the capacitor is V V whilst for circuit 2 the final voltage is (P P+S) V (P P + S) V with the chain of resistors acting as a potential divider. Note that as S → 0 S → 0 then (P P+S) V → V (P P + S) V → V which is circuit 1, and as P → ∞ P → ∞ then (P P+S) V → V (P P + S) V → V which is circuit 3.
Does connecting a capacitor across a resistor increase current?
@ADITYAPRAKASH, if the capacitor is initially not charged, and then you connect it across the resistor, you're right. It will momentarily drop the voltage across that resistor to 0. But no, the current will increase. Because now the whole voltage of the source is across the other resistor. and the current when does it resume then ?
What is the relationship between voltage and current in a parallel RC circuit?
In a pure capacitor the current leads the voltage by 90 degrees, while in a pure inductor the current lags the voltage by 90 degrees. Figure 1 Parallel RC circuit. The relationship between the voltage and currents in a parallel RC circuit is illustrated in the vector (phasor) diagram of Figure 2 and summarized as follows:
How to calculate voltage in a parallel circuit?
This being a parallel circuit now, we know that voltage is shared equally by all components, so we can place the figure for total voltage (10 volts ∠ 0°) in all the columns: Now we can apply Ohm’s Law (I=E/Z) vertically to two columns in the table, calculating current through the resistor and current through the capacitor:
Why do resistors and capacitors have the same impedance?
Because the power source has the same frequency as the series example circuit, and the resistor and capacitor both have the same values of resistance and capacitance, respectively, they must also have the same values of impedance. So, we can begin our analysis table with the same “given” values:
