Find the resistance of a conductor if the electric current flowing through it is 0.35 A when the potential difference across it is 1.4 V.
An electric lamp, whose resistance is 20 Omega and a conductor of 4 Omega resistance are connected to a 6 V battery as shown in (Fig. 3.18) Calculate. (a) the total resistance of the circuit, (b) the current through the circuit, and ( c) the potential difference across the electric lamp and the conductor. .
How much current flows through a 2kOmega resistor when a potential difference of 4V is applied across its ends?
How much current flows through a 2 k Omega resistor when a potential difference of 4 V is applied across its ends ?
How much current is flowing through a 1kOmega resistor when a potential difference of 2 V is applied across its end ?
Assertion : Potential measured by a voltmeter across a wire a always less than actual potential diference across it. Reason : Finite resistance of voltmeter changes current flowing through the resistance across which potential difference is to be measured.
How much current is flowing throught a 1k Omega rsistor when a potential difference of 2V is applied across its end ?
(a) What is meant by the ''resistance of a conductor''? Write the relation between resistance, potential difference and current. (b) When a 12V battery is connected across an unknown resistor, there is a current of 2.5 mA in the circuit. Calculate the value of the resistance of the resistor.
