Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
E.m.f. is defined as the
force on a charge
current per unit time
energy transferred to each unit of charge by the source
resistance of a cell
2.
A cell gives 18 J to 6.0 C of charge. The e.m.f. is
108 V
3.0 V
0.33 V
24 V
3.
Three 1.5 V cells in series have an e.m.f. of
4.5 V
1.5 V
3.0 V
0.5 V
4.
How much energy does a 9.0 V battery transfer to 20 C?
0.45 J
29 J
2.2 J
180 J
5.
The reading of a voltmeter across a cell is slightly less than its e.m.f. when a current flows because
the voltmeter is faulty
charge is lost
some energy is wasted inside the cell
the wires are thick
6.
The unit volt is equivalent to
A s
J C−1
C J−1
W A
