Phase shift between voltage and current

Click For Summary

Homework Help Overview

The discussion revolves around determining the phase shift between voltage and current in a circuit with a resistive load. The original poster presents a scenario involving a 100Ω load connected to a 100V power supply at 50Hz, noting specific instantaneous values for voltage and current.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to understand the implications of their findings regarding phase shift, while some participants question the need for additional information, such as a circuit diagram or a complete problem statement.

Discussion Status

Participants have noted that if the load is purely resistive, there should be no phase shift. However, there is a request for further details to clarify the context of the problem, indicating that the discussion is ongoing and exploring different interpretations.

Contextual Notes

The original poster mentions that the question did not include a circuit diagram, which may be relevant for fully understanding the problem setup.

Hello ,so am trying to find a phase shift between voltage and current ,I've done
Capture.PNG

what do i do after that ?and is this right ?

Q
A 100Ω load is connected to a power supply of 100V at 50Hz. At time, = 0, the instantaneous value for voltage across the load was zero and the current through the load was 0.7A.

If the load is resistive, there is no phase shift. Can you upload the circuit that goes with this question? In fact, it would help if you could upload or write out the full problem statement. Thanks.
