The power in an electrical circuit is given by the equation P = I2R, where I is the current flowing through the circuit and R is the resistance of the circuit. What is the power in a circuit that has a current of 0.1 amps and a resistance of 18 ohms?

0.18 watt

Explanation:

The following data were obtained from the question:

Current (I) = 0.1 A

Resistance (R) = 18 ohms

Power (P) =.?

P = I²R

Where

P is the power.

I is the current in the circuit.

R is the resistance.

With the above formula, we can obtain the power in the circuit as follow:

P = 0.1² × 18

P = 0.01 × 18

P = 0.18 watt

Therefore, the power in the circuit is 0.18 watt

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.
