Which circuit will not show current in ammeter ?

Which circuit diagram shows voltmeter V and ammeter A correctly positioned to measure the total potential difference of the circuit and the current through each resistor?

Consider a circular as shows in Fig. 6.5 (a). We want to measure the current i flowing in the circuit. For this we connect an ammeter of resistance R_(A) as shows in Fig. 6.5 (b). Find the percentage error in the current.

Draw a circuit diagram showing the use of an ammeter and a voltmeter.

In the circuit, the current is to be measured. What is the value of the current if the ammeter shown : (a) is a galvanometer with a resistance R_(G) = 60 Omega ,

The figure shows a circuit. When the circuit is switched on, the ammeter reads 0.5A. Calculate the value of the unknown resistor R.
