Phase shift between voltage and current

Click For Summary
SUMMARY

The discussion centers on determining the phase shift between voltage and current in a resistive load scenario. A 100Ω load connected to a 100V power supply at 50Hz exhibits no phase shift, as confirmed by the current measurement of 0.7A at time zero when the voltage is also zero. Participants emphasize the importance of providing a circuit diagram and a complete problem statement for clarity. The consensus is that for purely resistive loads, the phase shift is zero.

PREREQUISITES
  • Understanding of Ohm's Law and basic electrical principles

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.
