When the key K is pressed at time t = 0, then which of the following statement about the current I in the resistor AB of the given circuit is true?
Answers
When the key K is pressed at time t=0 . Which of the following statements about the current i in the resistor AB of the adjoining circuit is true Option 1) i=2mA at all Option 2) ... After sufficient time, steady state is reached; then there is no current in capacitor branch; so effective resistance of circuit is 1000+1000=2000 \Omega ...
the correct answer for the questin is At time t = 0 i.e. when capacitor is charging, current \[i=\frac{2}{1000}=2mA\] When capacitor is full charged, no current will pass through it, hence current through the circuit \[i=\frac{2}{2000}=1mA\].
A capacitor is a detached two-terminal electronic part that stores electrical vitality in an electric field.
The impact of a capacitor is known as capacitance.
While some capacitance exists between any two electrical channels in vicinity in a circuit, a capacitor is a part intended to add capacitance to a circuit.
