Charge flow
The total charge flowing in a circuit, calculated as:
Charge
(
C
) =
Current
(
A
) x
Time
(
s
)
Energy transferred
The
energy transferred
in a circuit, calculated as:
Energy
(
J
) =
Charge flow
(
C
) x
Potential difference
(
V
)
calculate energy transferred when charge flow is 3 coulombs and the p.d is 15v.
energy transferred =
45J
energy transfer is measured in
joules
