1)

The incorrect option is,

• A. from a to b

We know that electrons move in opposite direction to the conventional current from the figure.

The following figure shows the direction of conventional current passing through the circuit.

But the conventional current flows from positive to negative terminal of the battery it moves from ‘b to a’.

Hence, the correct option is,

• B. from b to a

Part 1

The conventional current through the resistor will go from b to a.

Explanation | Common mistakes | Hint for next step

Conventional current flows out of the positive terminal, through the circuit and into the negative terminal of the source

(2)

The incorrect option is,

• A. go from b to a

The following figure shows the direction of electrons passing through the circuit.

The electron current flows from negative to positive terminal of the battery.

Hence, the correct option is,

• B. go from a to b

Part 2

Electrons moving through the circuit will go from a to b through the resistor.

Explanation | Common mistakes

Electrons flow out of the negative terminal through the circuit and into the positive terminal of the source.

This is actual way of flow of current.

Answer

Part 1

The conventional current through the resistor will go from b to a.

Part 2

Electrons moving through the circuit will go from a to b through the resistor.
