WebAn ac circuit consist of a series combination of circuit elements X and Y. The Current is ahead of the voltage in phanse by 4 π . If element X is a pure resistor of 1 0 0 Ω. (a) name the circuit element Y. (b) calculate the rms value of current, if rms value of voltage is 1 4 1 V. (c) what will happen if the ac source is replaced by a dc source? WebNov 14, 2024 · An alternating current circuit is a flow of electrical current that alternates between two directions, typically 50 or 60 Hz. AC is used in homes and offices because it is more efficient than direct current (DC), and it can travel through more than one wire. AC is generated by devices called alternators.

WebIn AC circuits that contain capacitance, inductance, or both, the phase angles of current and voltage can differ from one another. That is, the current in the circuit may reach maximum or minimum at different times than the voltage. This time difference between alternating quantities is called phase difference and is expressed in degrees. Phase ...

WebSep 12, 2024 · Since the current in the circuit is the rate at which charge enters (or leaves) the capacitor, iC(t) = dq(t) dt = ωCV0cosωt = I0cosωt, where I0 = ωCV0 is the current amplitude. Using the trigonometric relationship cosωt = sin(ωt + π / 2), we may express the instantaneous current as iC(t) = I0sin(ωt + π 2). WebMay 4, 2024 · 05/04/2024.
