Why do you think it is essential to measure current in a series circuit instead of in a parallel circuit?

What would happen if you simply connected the current probe to opposite sides of the resistor?

Answer #1

Ammeter measures value of current flowing in circuit, so current should flow inside ammeter to give proper result. And it has very low resistance to ensure the correct measurement of current in the circuit.

If it is connected in parallel across any load then all current in circuit will choose lower resistive path (i.e ammeter) to cause it's circuit to be damaged. Hence it is used in series.

When connected on the opposite sides of the resistor, only the sign of the current value will change.

A voltmeter is a device placed in parallel with a circuit element to measure the voltage drop across the element. As it turns out, it is difficult (impossible?) to measure a voltage drop directly, so a voltmeter typically works by measuring a current and then converting to potential. At least before the days of digital circuitry, a voltmeter was basically an ammeter (which measures current) in series with a very large resistance R0. Suppose you use this kind of voltmeter...

Consider this circuit. In case there is a problem, here is the description: resistor B and a switch are in parallel, and this parallel combination is connected in series with a battery and with resistor A. The switch is now open. When the switch is closed, please describe what happens to each of the three quantities and why. The choices are increase, decrease, or stay the same, but be sure also to explain why each happens. a) current through A...
