Resistor A has twice the resistance of resistor B. When individually connected across a given potential difference, which one dissipates the most power; and when connected in series across the same potential difference, which one dissipates the most power?

Resistor B  when individually connected and Resistor A when connected in series.

Explanation:

Suppose Resistor B has resistance R then resistor A has resistance 2R.

When individually connected across a given potential difference Resistor B will dissipate more power because power is inversely proportional to resistance.

While when connected in series across the same potential resistor A will dissipate more power because resistor A will have more voltage and power is directly proportional to the square of the voltage.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
