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

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 moving coil galvanometer has a resistance of 900 ohm. In order to send only 10% of the main current through this galvanometer, the resistance of the required shunt is

A battery of e.m.f 6 V is connected to a resistor of 100 Omega through an ammeter of resistance 2Omega . If 50 mA current flows through resistor, find the itnernal resistance of the battery.

A resistor is connected to a battery of emf 10 V and internal resistance 0.3 Omega. What is the resistance of the resistor to be inserted in the circuit for the circuit current 1.2A?

A battery of e.m.f. 12 V and internal resistance 5Omega is connected to a resistor. If the current through the circuit is 0.3 A, what is the resistance of the resistor? What is the terminal voltage of the battery, when the circuit is closed?

Two cells of emf 2V and 4V and internal resistance 1Omega and 2Omega respectively are connected in parallel so as to send the current in the same direction through an external resistance of 10Omega. Find the potential difference across 10Omega resistor.
