The voltage and current in a conductor are measured as (50pm2)V and (5pm0.2)A The percentage error in the calculation of resistance is

When the voltage and current in a conductor are measured as (100pm4 ) V and (5pm0.2 ) A, then the percentage of error in the calculation of resistance is

In the experiment of Ohm's law, a potential difference of 5.0 V is applied across the end of a conductor of length 10.0 cm and diameter of 5.00 mm. The measured current in the conductor is 2.00 A. The maximum permissible percentage error in the resistivity of the conductor is :

In an experiment of calibartion of voltmeter, a standard cell of emf 1.1 V is balanced against 440 cm of potentiometer wire. The potentilal difference across the ends of a resistance is found to balance against 220 cm of the wire. The corresponding reading of voltmeter is 0.5 volt. Find the error in the reading of voltmeter.

When a potential difference of 2 V is applied across the ends of a wire of 5 m length, a current of 1 A is found to flow through it. Calculate (i) the resistance per unit length of the wire, (ii) the resistance of 2 m length of the wire. (iii) the resistance across the ends of the wire if it doubled on itself.

The voltage across a lamp is (6.0pm0.1)V and the current flowing through it is (4.0pm0.2)A . Find the power consumed with maximum permissible error in it.

A voltmeter having least count 0.1 V and an ammeter having least count 0.2 A are used to measure the potentail difference across the ends of a wire and current flowing through the wire respectively. If the reading of voltmeter is 4.4 V and reading of ammeter is 2.2 A, then find (i) the resistance of wire with maximum permissible error and (ii) maximum percentage error.
