ECE :: Network Analysis and Synthesis
-
In a series RLC circuit excited by e = Em sin ωt is seen that LC < 1/ω2. Then
-
A resistance R is connected to a voltage source Vs having internal resistance Rs. A voltmeter of resistance Rm is used to measure the voltage across R. The voltmeter will read
-
When a lead acid battery is being charged, the specific gravity of the electrolyte
-
Assertion (A): The response of a network to unit impulse can be obtained directly from the network function.
Reason (R): The response of a network for any input can be obtained from impulse response.
-
In the circuit shown in figure, for different values of R, the values of V and I are given. Other elements remaining the same. when R = ∞, V = 5 volt
- R = 0, I = 2.5 A
- R = 3 Ω, the value of V is given by
