A resistance potentiometer has a total resistance of 4 kΩ and is...
Ohms and a maximum power rating of 1 watt. If the potentiometer is used as a voltage divider with a 12 V source, what is the maximum current that can flow through the potentiometer without exceeding its power rating?
To find the maximum current, we need to use the power formula:
P = I^2 * R
where P is the power rating (1 watt), I is the current, and R is the resistance.
Rearranging the formula, we get:
I = sqrt(P/R)
Plugging in the values, we get:
I = sqrt(1/4000) = 0.05 A
Therefore, the maximum current that can flow through the potentiometer without exceeding its power rating is 0.05 A or 50 mA.
