Question 1
What formula is used to calculate instantaneous power?
- P(t)=V(t) + I(t)
- P(t)=V(t) ⋅ I(t)
- P(t)=V(t)/I(t)
💡 Hint: Think about how power is connected to both voltage and current.
Question 2
A power factor of 1 means that:
- True
- False
💡 Hint: Recall the definition of power factor and its implications.
