Answer:
The power dissipated if the three resistors were connected in parallel across the same potential difference is 405 W
Explanation:
Given;
three identical resistors connected in series
let the first resistor = R₁
let the second resistor = R₂
let the third resistor = R₃
Rt = R₁ + R₂ + R₃
Since the resistors are identical, thus, R₁ = R₂ = R₃ = R
Rt = 3R
Power is given as;
P = IV = V² / R
If the 3 identical resistor connection were changed to parallel, then the equivalent resistance in the circuit will be;
Therefore, the power dissipated if the three resistors were connected in parallel across the same potential difference is 405 W
<u>Answer:</u>
<h3>As electric current is carried in a cable, around it, a magnetic field is created. The lines of the magnetic fields form concentric circles around the wire. The direction of the magnetic field hinges on the direction of the current. It can be calculated by pointing the thumb of your right hand in the direction of the moment, using the "right hand law." The position of your curled fingers is in the magnetic field lines. The magnetic field magnitude depends on the sum of current, and the distance from the wire carrying the charge.</h3><u></u>
<u>Explanation:</u>
Determine the direction of vector B magnitude B:
Resultant magnitude strength: its direction is pointing to the left.
