Question

The ammeter and voltmeter readings for a circuit are as follows: V = 1.2 volts, I = 200mA Calculate the resistance and also its conductance.​

Answer 1

Answer:

Voltmeters are connected in parallel with whatever device’s voltage is to be measured. A parallel connection is used because objects in parallel experience the same potential difference. (See Figure 2, where the voltmeter is represented by the symbol V.) Ammeters are connected in series with whatever device’s current is to be measured. A series connection is used because objects in series have the same current passing through them. (See Figure 3, where the ammeter is represented by the symbol A.)

Answer 2

Answer:

Resistance=6ohms

Conductance=0.167mhos

Explanation:

The resistance of a simple circuit can be calculated using Ohm's law. By formula, it looks like this

R=V/I

Therefore, resistance is 1.2V/200mA or 1200mV/200mA. to get V value into mV value, we need to multiply it by 100; hence we get 1.2V as 1200mV. This gives us the value 6Ω.

The conductance value of any device is calculated by reciprocating the resistance value. In this case, it would be

1/6mohs. or 0.16666666mhos or 0.167mhos to be approximate.
