By mistake, voltmeter is connected in series and an ammeter in parallel. When the circuit is switched on

A

The main currnt in the circuit will be very low and almost all current will flow through the ammeter, if resistance of ammeter is much smaller than the resistance in parallel.

B

If the devices are ideal, a large current will flow through the ammeter and it will be damaged

C

If the devices (inculuding battery ) are idal, ammeter will read zero current and voltmeter will read the emf of cell

D

The devices may get damaged if emf of the cell is very high and the meters are nonideal.

Why is ammeter connected in series and voltmeter in parallel in the circuit?

By mistake, a voltmeter is connected in series and an ammeter is connected in parallel, with a resistance in an electrical circuit. What will happen to the instruments?

Assertion : If by mistake, a voltmeter is connected in series, then circuit will burn. Reason : Current will drastically decrease in the circuit.

The reading of ammeter and voltmeter in the given circuit is

Which statement/statement is/are correct? 1. An ammeter is connected in series in a circuit and a voltmeter is connected in parallel. 2. An ammeter has a high resistance. 3. A voltmeter has a low resistance.

An ammeter and a voltmeter are connected in series to a battery with an emf xi = 6.0 V . When a certain resistance is connected in parallel with the voltmeter, the readings of the latter decreases eta = 2.0 times, whereas the readings of the ammeter increase the same number of times, Find the voltmeter readings after the connection of the resistance.

If a voltmeter, in advertently mistaken for an ammeter, were inserted into the circuit, the current

An ammeter, voltmeter and a resistor are connected in series to a cell and the readings are noted as I and V. If another resistor R is connected in parallel with a voltmeter, then

An ammeter and a voltmeter are initially connected in series to a battery of zero internal resistance. When switch S_(1) is closed the reading of the voltmeter becomes half of the initial, whereas the reading of the ammeter becomes double. If now switch S_(2) is also closed, then reading of ammeter becomes :

An ammeter and a voltmeter are connected in series to an ideal battery of emf E. If the ammeter reads I and voltmeter reading V, then
