A resistance of 1kΩ has a current of 0.25A throughout it when it is connected to the terminal of a battery. What is the potential difference across the ends of a resistor?

The potential difference across the resistor is 250 volts.

Explanation:

The potential difference across the ends of the resistor is given by

where is the current through the resistor and is is its resistance.

Now, in our case

,

;

therefore, the potential across is

be subject to a force andchange its motion

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
