Solution

The correct option is C decreases
Voltmeter has high resistance and because it is connected to the circuit in series. So, net resistance of the circuit increases. So, current in the circuit decreases.

Q. Assertion :All electric devices shown in the circuit are ideal. The reading of each of ammeter (a) and voltmeter (V) is zero. Reason: An ideal voltmeter draws almost no current due to very large resistance, and hence (V) and (a) will read zero.

Q. In the following circuit diagram (fig) if the ammeter reading is zero, then the voltmeter reading will be

Q. The current in a conductor and the potential difference across its ends are measured by an ammeter and a voltmeter. The meters draw negligible currents. The ammeter is accurate but the voltmeter has a zero error (that is, it does not read zero when no potential difference is applied). Calculate the zero error if the readings for two different conditions are 1.75 A, 14.4 V and 2.75 A, 22.4 V.

Q. What should I choose ______________.
a. For decreasing resistance in a circuit.
(Resistors in series / Resistors in parallel)
b. For getting protection from electric current.
(Nickel / Ebonite)
c. To measure the current in the circuit.
(Ammeter / Voltmeter)
