Physics questions on electrical circuit?
1. In the water flow circuit analogy, the unit of a gallon would correspond to the unit of a(n)_________. (Ohm, Coulomb, Amp, Volt)
2. Explain what it means to say that "circuit elements are connected in series"?
3. The multimeter is able to measure a number of electrical quantities. In which roles (ammeter, voltmeter, Ohmmeter) does it have the largest and smallest resistance and why?
I know the largest resistance is Voltmeter and the ammeter has the smallest, but I dont know why. I think it has something to do with so it won't use up all the electricity or something.
Both volt meter and amp meter always should draw very less current to show measurement almost accurately.
