What is the relationship between power, voltage, and current in an electrical circuit?
P = V/I
P = VI
P = V + I
P = V - I
Questions & Step-by-Step Solutions
What is the relationship between power, voltage, and current in an electrical circuit?
Correct Answer: P = VI
Step 1: Understand the terms: Power (P) is how much energy is used, Voltage (V) is the force that pushes electric current, and Current (I) is the flow of electric charge.
Step 2: Learn the formula: The relationship between power, voltage, and current is expressed by the formula P = VI.
Step 3: Break down the formula: This means that to find power, you multiply voltage (V) by current (I).
Step 4: Example: If you have a voltage of 10 volts and a current of 2 amps, you can calculate power as P = 10V * 2A = 20 watts.
