3.

A cell of e.m.f. 1.5 V and internal resistance 0.50 Ω is connected to a 2.5 Ω resistor. What is the current?

0.60 A
3.0 A
0.50 A
0.75 A
4.

For the cell in a circuit, the terminal potential difference is less than the e.m.f. because

charge is used up in the circuit
some energy is dissipated in the internal resistance
the current is lower inside the cell
the e.m.f. falls to zero
5.

9.0 Ω
4.5 Ω
2.0 Ω
0.50 Ω
6.

4.0 V
6.0 V
8.0 V
12 V
7.

In a potentiometer, the balance point is found when

the current in the wire is zero
the galvanometer reads zero
the cell is flat
the wire is at maximum length
8.

The e.m.f. of a source is

the energy dissipated per unit charge in a resistor
the force on a unit charge
the energy transferred from other forms to electrical energy per unit charge
the current per unit resistance
9.

Three identical resistors, each of resistance R, are connected in series. Their total resistance is

R/3
R
