Jason sees a news report about a traffic jam caused by a truckload of tires that spilled across the road. the next day in class, he uses the traffic jam as an analogy to explain electric circuits to his friend. which is most likely the analogy that jason used? a) the cars represent moving charges, and the spilled tires represent an increased voltage that causes the current to decrease. b) the cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease. c) the tires represent moving charges, and the cars represent an increased resistance that causes the current to decrease. d) the tires represent moving charges, and the cars represent an increased voltage that causes the current to decrease

B) The cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease.

Option B: The cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease.

Explanation: In the street, the spilled tires decreased the amount of space that the cars had to move, so it can be called a "resistance against the movement of the cars"

So we can think in the cars as moving charges, that in a given point of the circuit, they find something that "resists" against their movement, this is the spilled tires, and this is equivalent to the resistance in a circuit. So the correct option is the B: The cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease.

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
