The e.m.f of a cell is 1.5 $V$ . What is the energy provided by the cell to drive 0.5 $C$ of charge around the circuit?

[Note: Enter the answer up to three decimal places.]

$q$

$=$ 0.5

$C$

$ϵ$

$=$ 1.5

$V$

The formula of e.m.f is

$ϵ = \frac{i}{i}$

The above formula can be written as

$W\ =$ $q \times{\epsilon}$
$W\ =$ $\epsilon \times{q}$

$W = \frac{i}{i}$

The energy given by the cell is

$J$ .
