Acurrent of 9 a flows through an electric device with a resistance of 43 ohms. what must be the applied voltage in this particular circuit?

a. 387 v
b. 4.8 a
c. 387 a
d. 4.8 v

Use Ohm law

Voltage = (current) x (resistance). = ( 9 A ) x (43 ohms) = 387 volts.

Answer is A 387 V DO NOT make a mistake and check 387 A

the answer for apex is the lowest

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.
