the question is:
when terminals of a cell of emf 1.5V are connected to ammeter of resistance 4ohm, the ammter reads 0.30amp. which of the following statements is/are correct?
1. the cell is non ideal
2. if a 4ohm resistor is also connected across terminals of the cell, the ammeter will read 0.50 amp.
3. if a 4ohm resistor is also connected across terminals of the cell,one third of the elctrical power generated will as heat within the cell.
4. suppose a voltmeter of resistance 4ohm is used to measure potential difference between the terminals of the cell, it will read 1.2V
