For the measurement of potential difference, voltmeter is connected

Assertion: An inductance and a resistance are connected in series with an AC circuit. In this circuit the current and the potential difference across the resistance lag behind potential difference across the inductance by an angle pi//2 . Reason: In LR circuit voltage leads the current by phase angle which depends on the value of inductance and resistance both.

A student measure the terminal potential difference (V) of a cell (of emf internal energy is connected in providing the circuit is

(a) With the help of a circuit diagram, deduce the equivalent resistance of two resistances connected in series. (b) Two resistances are connected in series as shown in the diagram: (i) What is the current through the 5 ohm resistance? (ii) What is the current through R? (iii) What is the value of R? (iv) What is the value of V?

A voltmeter of resistances 400(Omega) is used to measure the potential difference across the 100(Omega) resistor in the circuit shown in figure.(a) What will be the reading of the voltmeter ?(b) What was the potential difference across 100(Omega) before the voltmeter was connected ?

A 12Omega resitance and an inductance of 0.05/ piH with negligible resistance are connected in series. Across the end of this circuit is connected a 130 V alternating voltage of frequency 50Hz. Calculate the alternating current in the circuit and potential difference across the resistance and that across the inductance.
