What is resitance ?

Two resistors R_(1)andR_(2) are connected in parallel. What is equivalent resitance ?

The circuit shown here is used to measure resitance R. An ammeter shows a current of 2A and a voltmeter of a potential difference of 120 V. what is the resitance R if the internal resistance of the voltmeter is R_(v) = 3000 Omega ? How large will the error in measuring R be, if the resistance of the voltmeter is assumed to be infinitely large?

What do you mean by equivalent resistance resitance ?

In the circuit (Figure ) , the current it to be measured. What is the value of the current if the ammeter shown (a) is galvanometer with a resitance R_(G) = 60,00 Omega , (b) is a galvanometer by a shunt resitance r_(s) = 0.02 omega (c) is an ideal ammter with zero resitance ?

Define heat resitance. Write the SI.. unit of heat resistance.

It is desried to pass only 5% the current through a galvanometer of resitance 95 ohm. What shunt resistance should be connected across it?

A capacitor of capacitance C is given charge Q and then connected in parallel to a coil of inductance L. There is no resitance in the circuit. When the charge on the capacitor becomes zero, the current in the coil will be

Temperature coefficient of resistance of a wire at 0^(@)C is 0.00125^(@)C^(-1) . At 25^(@)C its resistance is 1 Omega . The resitance of the wire will be 1.2 Omega at
