When placed in a circuit a ammeter acts like a short circuit.
True
False
Homework Answers
True
An ammeter is connected in series with the circuit because the purpose of the ammeter isto measure the current through the circuit. Since the ammeter is a low impedance device, connecting it in parallel with the circuit would cause a short circuit, damaging the ammeterand/or the circuit.

2. (Short Circuits) An Ammeter is a device that can measure current through a circuit compo- nent. It is devised to be a device that has a VERY LOW internal resistance r. You use the device by connecting the device in series with the branch of the circuit you want to measure the current through. Suppose you accidentally connected the ammeter in parallel with a bat- tery and another resistor (with resistance R»r). Using Kirchoff's rules, show that when s...

If we say that something acts as a "short circuit," it means that the path has very low resistance to current flow. Which of the following represents a situation that could be described as a "short circuit?" a capacitor in a circuit with a very low frequency AC generator a resistor in a circuit with a very low frequency AC generator a capacitor in a circuit with a high frequency AC generator a resistor in a circuit with a high...

i) _________ True or False. A force with a strength of 50 Newtons acts on two different objects: a car and a truck. Because the force on the truck is the same as the force on the car, both vehicles will experience the same acceleration. Explain your reasoning. ii) Give an example of rotational motion. iii) When the net torque on an object is zero, the object will a) continue to spin in the same direction (clockwise or counterclockwise) b)...
