Can the potential difference across a battery be greater than its emf?

Find the potential difference across C_2.

Assertion: In an AC circuit, potential difference across the capacitor may be greater than the applied voltage. Reason : V_C=IX_C , wheereas V= IZ and X_C can be greater than Z also.

A high resistance voltmeter measures the potential difference across a battery to be 9-0 V. On connecting a 24 2 resistor across the terminals of the battery, the voltmeter reads 7.2 V. Calculate the internal resistance of the battery.

What is terminal potential differnce of a cell? Can its value be greater than the emf of a cell? Explian.

An inductor of inducance 5.0 H, having a negligible resistance, is connected in series with a 100 Omega resistor and a battery of emf 2.0 V. Find the potential difference across the resistor 20 ms after the circuit is switched on.

A voltmeter of resistance 994Omega is connected across a cell of emf 1 V and internal resistance 6Omega . Find the potential difference across the voltmeter, that across the terminals of the cell and percantage error in the reading of the voltmeter.

A voltmeter having a resistance of 1800 Omega employed to measure the potential difference across a 200 Omega resistor which is connected to the terminals of a dc power supply having an emf of 50 V and an internal resistance of 20 Omega . What is the percentage decrease in the potential difference across the 200 Omega resistor as a result of connecting the voltmeter across it?
