Q1PhysicsUnit 12: Current Electricity

A straight conductor of uniform cross- section carried a current I. Let s=specific charge of an electron. The momentum of all the free electrons per unit length of the conductor, due to their drift velocities only, is

Q2PhysicsUnit 12: Current Electricity

In the circuit shown, the heat produced in

5 \Omega

resistor is 10 calorie/sec. The heat produced/sec in

4 \Omega

resistor will be :

Q3PhysicsUnit 12: Current Electricity

In a metallic conductor, electric current is thought to be due to the movement of

Q4PhysicsUnit 12: Current Electricity

The equivalent Resistance: This question has multiple correct options

Q5PhysicsUnit 12: Current Electricity

Between any two points in a circuit, the sum of all

\ldots \ldots . . . . . . .

is the same through any pathway.

Q6PhysicsUnit 12: Current Electricity

Q Type your question- and of fixed emf, the resistor

\boldsymbol{R}_{1}

has fixed resistance and the resistance of resistor

\boldsymbol{R}_{2}

can be varied (but

\boldsymbol{R}_{2}

is always nonzero). Then the electric power delivered to the resistor of resistance

R_{1}

is independent of the value of resistance

\boldsymbol{R}_{2}

Reason f potential difference across a fixed resistance is unchanged, the power delivered to the resistor remains constant.

Q7PhysicsUnit 12: Current Electricity

Fuse wire should be placed in the path of wire

Q8PhysicsUnit 12: Current Electricity

There are a large number of cells available, each marked

(6 V, 0.5 \Omega)

to be used to supply current to a device of resistance

0.75 \Omega,

requiring

24 A

current. How should the cells be arranged, so that power is transmitted to the load using minimum number of cells?
