What is the relationship between current (I), power (P), and voltage (V)?
Question

What is the relationship between current (I), power (P), and voltage (V)?

A.

I = P2V

B.

I = PV

C.

I = V ÷ P

D.

I = P ÷ V

Correct option is D

The correct answer is D  (I = P ÷ V).

Explanation:

  1. Relationship Between Current (I), Power (P), and Voltage (V):
    • Electric power is given by the formula: P=V×I where:
      • P is power (in watts),
      • V is voltage (in volts),
      • I is current (in amperes).
  2. Rearranging the Formula:
    • To find I, divide both sides of the equation by V:

I=PVI = \frac{P}{V}​​

Conclusion

    • Current is directly proportional to power and inversely proportional to voltage.

Key Points:

  •  Formula: P=V×I
  • Current I=PVI = \frac{P}{V}​​
  • This relationship is crucial for calculating the current in electrical circuits.
