Three resistances are connected to a battery as shown in the diagram. Find the value of current in the circuit.

Resistances 2ohm, 4ohm and 6ohm are connected in series with a battery of emf 6V. Find the current in the circuit. What is the current when the resistances are connected in parallel

A resistance R is connected to a cell of EMF E and has an internal resistance r as shown in the figure. The voltage across R is measured using and ideal A voltmeter and circuit current is measured by an ammeter. A rheostat of negligible resistance is used to vary the current in the circuit. -Write down the expression for current in the circuit and voltage across R at any instant.

Three resistances R, 2R & 3R are connected In parallel to a battery. Then heat is maximum In.

A battery of emf 10V and internal resistance 3Omega is connected to a resistor.If the current in the circuit is 0.5A,what is the resistance of the resistor? What is the terminal voltage of the battery when the circuit is closed?

A battery of e.m.f. 10V and internal resistance 3W is connected to a resistor. If the current in the circuit is 0.5A, what is the resistance of the resistor? What is the terminal voltage of the battery when the circuit is closed?
