Question
When a resistor carries a current "I" its power dissipation is "P". If the same resistor carries the current of "3 I" the power dissipation will be:
Solution
The power dissipation in a resistor is given by the formula P = I^2 * R, where I is the current and R is the resistance.
If the current is tripled, the new power dissipation P' will be given by P' = (3I)^2 * R = 9I^2 * R.
Therefore, the power dissipation will be 9 times the original power dissipation when the current is tripled.
